This is a bug that was introduced recently and effects a small subset of Macs with integrated Intel graphics.

Fortunately, we have a beta test version that fixes this issue. 

For Mac and PC owners of a previous version of the program (v2.6 and earlier), there are a few different upgrade paths depending on where you purchased the product.  

• Keycodes purchased from the SereneScreen website, go here. 
• Keycodes purchased from 3rd party (i.e. Avanquest, MacUpdate, etc), please read this entry.
• For CD owners (v2.6 and before, XP Plus version not eligible for upgrade) please read this entry. 

The Android and iOS version do require any upgrades.

Slow animation, jittering, or freezing can be caused by a variety of things. Let's try a few of the basics and see what might be causing the issue:

1. Start the program, hit the "S" key. This will display a number of statistics in the upper left-hand corner of the aquarium. Locate "Sleep".  Using up arrow key on your keyboard raise this setting to thirty (30).
2. Examine the programs in your System Tray.  If there is an icon indicating Windows or another program is waiting to update, run these updates.
3. If the icon is not one of your basic system functions (volume, task manager, mouse, video card, printer, etc.) exit, disable or close the program.
4. Double-check your computer for spyware or viruses.

If none of the above solves your problem, please contact us.

Slow, jittery, or frozen graphics are most often caused by low video resources. The best way to improve performance is to complete ALL of the following steps:

1. Start the program and hit the spacebar.
2. Select the Settings tab.
3. Turn off the Bubble Column.
4. Now select the Fish tab.
5. Reduce the number of fish to zero.

After finishing all of these steps, take each setting back to default to see where the problem is solved.

There are two reasons that this can happen:

1. If Marine Aquarium runs for a while then goes black, this can be caused by the monitor going into sleep mode. Check your Power Options in the Windows Control Panel. 
2. If Marine Aquarium goes black as soon as it activates, this can be a problem with your video card driver.  Check this section of our FAQ for more info on driver updates.

Marine Aquarium runs on a few different platforms.

Selecting Individual Fish - To select a fish, just mouse over the kind you want and left click, a box will appear around it. The number to the lower left of the fish will tell you how many of this specific kind will appear in the tank, no number to the left of the fish means the fish is set to appear randomly. An "X" next to the fish means that this kind is "turned off" and will not appear in the tank until you turn it back on, as outlined in the Individual Fish Population section below.

Fish Information Box - On the top left you will find vital information on the fish you have just selected.

Populating the Tank

Clicking on the arrows to the left of this number will correspondingly increase or decrease the overall population of the tank.

Setting Individual Fish to "Random" - Clicking the down arrow to none will bring up a "?" which sets the fish to "Random". This fish will now randomly appear in the tank every time you start the program (assuming you have any random slots assigned, more on this below)

Setting Individual Fish to "Off" - Clicking the down Arrow past the "?" will turn the fish off, effectively removing it from the tank until you choose to change this setting. Alternatively, you may simply click the "Disable Fish" box.

All of the information about your video driver is on the right-hand side under the heading Driver.

• Version
• Date

Click "Save All Information".  Keep this file around for future reference.

If you are experiencing graphical issues or poor general system performance while running the program, you may want use this information to update your video driver.

Due to the extra security and new file structure of the 64bit version of Windows, you will need to perform one extra step to install the Aquarium on your computer:

Download the installer.  Double left-click the installer and follow the instructions.

Confirm the installation by checking the screen saver list again.

If this does not solve your problem, please contact us with a description of the problem.

If you are experiencing problems with graphical glitches or poor framerate you may need to update your video drivers.  We have found that outdated/corrupted drivers are the number one reason for most graphics/performance problems. 

PLEASE NOTE - Windows Update function is often not sufficient for updating your video card drivers.  Any time you update drivers, be sure to create a restore point and back up your system. 

IMPORTANT:  We recommend using manufacturer's automated update tools.  If for any reason you need to install your drivers manually, carefully read the documentation on the individual manufacturer's website regarding driver updates and be sure to secure your system as noted above.

Desktop 

• Using the information you gathered here, you will need to go to the manufacturer's website.  AMD, Intel, and Nvidia all have useful automated systems to detect and update your drivers.

Laptop

• Go to the laptop manufacturer's website (i.e. Lenovo, HP, Dell, etc.) and search their support section or utilize their automated tools to update video drivers related to your specific model of laptop.
• If for any reason the laptop manufacturer drivers are not working or you aren't happy with performance, you can try GPU manufacturer drivers.  Using the information you gathered here, go to the manufacturer (AMD, Intel, or Nvidia) that corresponds to your video hardware.

If this does not solve your problem, please contact us.

The Transparent Fish issue is a bug that was introduced recently and effects a small subset of Macs with integrated Intel integrated graphics. 

We do have a fix for this issue, however, you'll need to fully uninstall v3.2 and install the Beta 3.3. 

As a bonus, we've added Feather Dusters to the tank (net to the bubble column) in this update.

To uninstall Marine Aquarium please follow the instructions below:

1. Open a Finder window
2. Search for "Marine Aquarium" (without quotation marks).
3. Drag each file you find into the Trash.
4. Next, with the Finder still open, press Command+Shift+G on your keyboard to bring up the "Go to the folder" panel.
5. Enter "~/Library" (without quotation marks) and click "Go".
6. Open the "Screen Savers" folder.
7. Search for "com.prolific"(without quotation marks).
8. Drag each file that you find into the Trash and empty it.
9. Next, simply download the Marine Aquarium 3.3 Beta and install as normal.  

• NOTE: Be sure to copy and paste your keycode into the registration space.

IMPORTANT: Marine Aqurium 3.3 for MacOS is still in Beta and there are a few known issues.

1. The “Show FPS” option does not work. The text message in the aquarium showing the frames per second measurement is not displayed.
2. The fade between two backgrounds does not work. The new background “snaps” into place at the end of the transition. The foreground lighting transition does occur correctly."

If you encounter any other problems or bugs to report, please contact us.  Your feedback is invaluable.

Slow animation, jittering, or freezing can be caused by a variety of things. Let's try a few of the basics and see what might be causing the issue:

1. Start the program, hit the "S" key.
2. In the upper left-hand corner of the Aquarium, locate "Sleep".  Using up arrow key on your keyboard raise this setting to thirty (30).
3. Examine the programs in your System Tray.  If there is an icon indicating Windows or another program is waiting to update, run these updates.
4. If the icon is not one of your basic system functions (volume, task manager, mouse, video card, printer, etc.) exit, disable or close the program.
5. Double-check your computer for spyware or viruses.

If none of the above solves your problem, please contact us.

Slow, jittery, or frozen graphics are most often caused by low video resources. The best way to improve performance is to complete ALL of the following steps:

1. Start the program and hit the spacebar.

2. Select the Settings tab.
3. Turn off the Bubble Column.
4. Now select the Fish tab.
5. Reduce the number of fish to zero.

After finishing all of these steps, take each setting back to default to see where the problem is solved.

There are two reasons that this can happen:

1. If Marine Aquarium runs for a while then goes black, this can be caused by the monitor going into sleep mode. Check your Power Options in the Windows Control Panel. 
2. If Marine Aquarium goes black as soon as it activates, this can be a problem with your video card driver.  Check this section of our FAQ for more info on driver updates.

If you own MA3, please check the Marine Aquarium settings menu. From the Settings menu click on the Display Settings button, each monitor should have a "Tab".

Please makes sure that you have Display screen saver on this monitor selected on each tab. Make sure you cycle through ALL your monitor tabs when checking this setting.

If you have Marine Aquarium 2.5 or 2.6, please look in the Marine Aquarium settings menu. Double-check you do not have the "Black" option checked for any of the monitors that are giving you trouble. Scroll through the monitor's list and check each one individually.

If you have Marine Aquarium 2.0 or Marine Aquarium TIME 2.0, you will want to download and install the special MD version that includes the features above:

Marine Aquarium 2 MD

Marine Aquarium Time 2 MD

We have found that Marine Aquarium can be stopped or minimized by Windows when another device or program steals priority from your system's processor. This can be caused by many things, including the following:

• Wireless hardware, like mice and keyboards, send signals to the computer that can prevent Windows from calling up a screen saver. Try updating the drivers for your wireless devices.
• Programs running in the background. Nearly all computers have programs and utilities running in the background, not noticed, but requiring resources to operate. Some of these programs are less obtrusive than others.

To address these possibilities:

1. Examine the programs in your System Tray.  If it is not one of your basic system functions (volume, task manager, mouse, video card, printer, etc.) exit, disable or close the program. 
2. Make sure Windows Update isn't waiting to install anything.
3. Viruses and spyware can steal a lot of system resources; in fact, this is one of the symptoms of being infected with this malevolent software. Update and run your antivirus program. Do a full system scan to be sure that your computer is clean.

1. If you are not hearing sound when the program starts please check the "Program Settings". Make sure there are checks in the boxes next to Music and Bubble Sound.
2. If you still cannot hear any sounds please make sure that your speakers are properly connected and set up.
3. Failing that you will need to try updating or reinstalling your sound card driver.

AutoCAD or some other program has changed the association of the .scr file type, meaning Windows no longer sees files with the .scr extension as screen saver files, but as another type of file. While Marine Aquarium will run normally as a screen saver, you cannot use the Aquarium shortcut on your Desktop. Here is a way to work around that:

1. Open a File Explorer window
2. Click the View tab, uncheck File name extensions and click the Apply button. This will allow you to view the file extensions for all files.
3. Close your File Explorer window.
4. Right-click on the Marine Aquarium 3 desktop shortcut and select Properties. This will bring up the Shortcut properties window.
5. Click the FIND TARGET... button at the bottom of the Shortcut properties window. This will take you right to the MarineAquarium3.scr file on your hard drive.
6. Right-click the MarineAquarium3.scr file and select Copy.
7. Go back to your Desktop, right-click any empty space and select Paste. A copy of MarineAquarium3.scr should appear on your Desktop.
8. Right-click on the new MarineAquarium3.scr icon and select Rename from the menu.
9. Change the icons name to MarineAquarium3.exe.
10. Delete the old Marine Aquarium 3 shortcut from your Desktop.
11. You can now run Marine Aquarium 3 manually by double-clicking the new icon.
12. If you are using an older version of Marine Aquarium, the above instructions are the same except for the program's file name.

Please make sure that you have installed the .saver file in your Harddrive/Library/Screensaver folder and not your User/Library/Screensaver folder. This is the most common reason for the problem you are describing.

However, if this still doesn't solve the problem please try the following.

1. From the Apple menu, choose System Preferences, then click Desktop & Screen Saver.
2. Click the Screen Saver tab. Screensavers appear on left side of the window, and a preview of the selected screen saver appears on the right.
3. Scroll the list and select Marine Aquarium 3 from the list. To see a full-screen preview, move your pointer over the preview, then click the Preview button that appears within.

If this does not solve your problem, please contact us.

Pressing the F key will switch the Marine Aquarium to full-screen mode.

This can happen if your Energy Saver options are set to put the computer or monitor to sleep at the same time Marine Aquarium is set to activate. To check this, do the following:

1. Click on the Apple Menu and select your System Preferences.
2. When the System Preferences window comes up, click on the Energy Saver icon.
3. Check to be sure that the "Turn display off after..." options are set beyond the time that you have Marine Aquarium active. In other words, if you have Marine Aquarium set to come on in five minutes, the Energy Saver settings will have to be longer than five. We recommend at least fifteen minutes between the two settings.

This was intentional, as we wanted to allow users to be able to have the program running on one monitor while working on another. Relax and listen to iTunes with our playlist manager and watch our fish swim while you work!

If you want the full multi-monitor experience simply wait for the Marine Aquarium to start as your screensaver or access it through your >System Preferences>Desktop and Screensaver and hit the Test button.

By default, Marine Aquarium is installed into the C:WINDOWSystem32 folder. This can be changed during installation.

Different versions of Marine Aquarium use different file names that you may need to know for reinstalling the program or altering the file extension.

The Marine Aquarium uses every bit of graphics power it can to produce the amazing and beautiful images and animations you see.

Please try a mix of the following :

• In order to save resources, try lowering the number of fish.  We have a number of optimization features that can help automate this.
• Turn off Bubbles.
• Turn on Wireframe mode.  Try a mix of fish and background combinations.
• Use the battery drain feature in Optimize.

If this does not help we suggest only using Marine Aquarium while plugged in.

Starting with iOS 11, Apple began requiring all Apps to be compiled as 64-bit programs. 

Devices on iOS 10 and earlier can access the app, but it will not show up in the App Store for users of iOS 11. 

We are working on an update that will bring the program up to date with the most current operating system, but we have no information on when it will be ready.

There is a bug with this feature, we will be improving the feature in future updates.  

There is a workaround that works for some people.

1. Menu>Wallpaper/Daydream: Remove the check mark from "Lock screen to one orientation" then close and restart the app.
2. Menu>Panning: Turn off Panning in the app, then go into the Aquarium and manually center the Crystal.
3. Menu>Wallpaper/Daydream:  Turn "Lock screen to one orientation" on and set the orientation you to what you set in the tank.

If none of the above solves your problem, please contact us.

Screensavers were originally designed to help avoid the effects of burn-in by automatically changing the images on the screen when the computer was not in use (thus "saving" the screen from burn-in). They are usually set up to launch automatically by the computer's operating system, waiting a specified amount of time after the last keystroke or the last mouse movement made by a user. The screen saver then blanks the screen, or more commonly produces animation effects, thus avoiding any "fixed" images.

Modern monitors are much less susceptible to burn-in than older models due to improvements in technology and the addition of energy saver options. For these reasons, screensavers today are primarily decorative or for entertainment, and usually feature moving images or patterns and sometimes sound effects.

Our LifeGlobe and SereneScreen products are hyper-realistic simulators. They model real creatures in real environments. They are completely unpredictable and follow behaviors modeled after their real-life counterparts.

As a result, the background can remain on screen for long periods of time without change.

By default our simulators ship in a mode that cycles the background and/or lighting. Changing these options can affect some monitors over a long period of time. If you are concerned about burn-in, do not turn off this cycle.

Burn-in is a generic term for a ghost-like image that appears on a monitor or television after displaying an image that does not change for a long period of time.

Burn-in is also called ghosting or image persistence. While the exact cause is different for different types of monitors, the result is the same, a light or dark area of the screen where the non-moving image was displayed.

Due to improvements in technology, energy saver options, and screensavers, burn-in is much less of a problem than in the past. However, any program, even a screen saver, can cause burn-in if left running long.

Most computers have several layers of protection against burn-in:

Better technology

Advancements in monitor hardware and software mean that today's monitors are less likely to burn-in.

Energy saver options

To save electricity, monitors will switch to an energy saving mode after a period of time, either reducing the brightness of the display or turning off the display entirely.

Screensavers

Finally, there are an incredible number of screensavers that display moving images to reduce the persistence of a single image on the screen helping to avoid burn-in.

However, even with these advancements and options, in rare cases, burn-in can still occur. To prevent burn-in, we recommend the following:

Different monitors have different needs when it comes to burn-in. You should check the users manual for specific information, or even contact the manufacturer, just to be sure what steps you can take for your specific monitor.

Set the energy saver options to turn off your monitor when not in use for a long period of time.

With any of our products older products, the background and foreground lighting change constantly on an automatic cycle. If you are concerned about burn-in, do not turn off this cycle.

MA3 is different than the MA1 or MA2 series of our products in that it does not have an automatic light cycle, instead, the program pans from right to left which creates a constantly moving background which should help your monitor prevent burn-in. Changing this setting, or stopping it will increase the risk of burn-in and should be done so with caution.

This depends on the kind of monitor you have.

CRT

Unfortunately, once burn-in occurs on a CRT monitor, there is no fix as the actual process that produces the image has been damaged.  This is an outdated technology and there are very few in use these days.  However, if you happen to be using one, this is the most "at risk" type of monitor.

LCD & Plasma monitors

The approach to fixing burn-in on plasma and LCD monitors is the same: Display a white screen on the display for a length of time equal to the image that burned-in.

Apple has an excellent article on how to go about this:

Apple: Avoiding image persistence on Apple LCD displays

This process will work with any LCD, not just Apple LCD displays.

Roku now offers SereneScreen Marine Aquarium (Aquatic Life) as the default screensaver exclusively on it's 4K streaming devices.

Now you can now help relieve the stress of the day by turning your UHD 4K display into a beautiful high definition Aquarium.  Best of all no tank maintenance or fish food required!

Marine Aquarium currently includes the following twenty-nine fish:

Wireframe mode strips away the textures or "skin" of the fish to reveal the polygon wireframe beneath. 

It is implemented in a slightly different way between PC/Mac and Android.  Wireframe mode is not available on the iOS version.

PC/Mac

Android

Currently, we do not permit people to create or add custom fish for Marine Aquarium. There are many reasons, but the most important is that while we trust an artisan would be motivated, and even capable of creating a truly wonderful masterpiece, there are others that might not, and if a version were to get out that was less than the highest quality, it might reflect poorly on us.

If you are interested in creating fish or wildlife for our company, we are always seeking talented artists. Please contact us with samples of your work.

Thank you for your support.
