I couldn't figure out why my aquarium is sooooo gross when I have a canister filter and only one turtle. There is so much crud on the bottom its unbelievable and I was being so careful not to over-feed. As it turns out, I was feeding the turtle 2-3 times per week-- and my son (age 12) was feeding him daily, and my daughter as well! And that naughty little turtle still acted like he was starving to death every time I fed him! I'm suprised he is not as big around as a garbage can lid by now!
