New ATI "fix" dosn't solve redout prob.
 

ATI just updated their October Radeon software, but it doesn't affect the "midnight blue" look of Aquarium. Jim O'Conner had notified them of the problem and they said a fix would be available soon - but this ain't it. Oh well...

I'm pinging Apple again.

It worked for me the second time!
 

Try installing it again. I don't know why I did it twice, but for some reason I did. The first time it had no effect at all... it still looked like I had poured a half a bottle of Rid-Ich in my tank, but after I did it again... restarting both times, my Aquarium is back to normal!!! Sooooo nice to have it again!!! Try installing the new ATI update couple more times if necessary. I hope it works for you!

ATI Problem fixed
 

Thanks for your suggestion on VersionTracker.com, MrTew - Simple reinstalling did nothing, but I saw on your post there that when the update asked for a restart was when you were tipped off to the solution. I trashed my ATI utilities folder and reinstalled update (also chose a specific folder for installation, rather than simply the default OS X disk). It asked for a restart - first time in four installations - and Aquarium looks fine! ATI should suggest deleting application software before updating. Thanks for your help and suggestions, guys!

Its Fixed!
 

Just wanted to mention, the color shift problem has been fixed for me. I had a similar issue with the new update. The first time I installed it, it did not request a restart and Marine Aquarium still looked bad. However, after re-installing the ATI update a 2nd time, it asked for a restart and Marine Aquarium looks fine.

Except for the jaggies. :-(
