Thanks everyone.
I actually left the bottom front for the otto's, pleco, and chinese algea eater, others eat a bit too. It's gone now, can't have a completely algea-free tank, that's no good.
My water is fairly hard, though it is softened through 3 filters in the home, it's well water, naturaly chlorine free etc, thats what I use. Maybe that has something to do with it.
I've heard of the Timer light, and I've looked around for one but havent seen any in any lfs, I will buy a few for my tanks if I find them though.
BTW, the Moonlights look badass, haven't seen any of those either, next time I go to Big Al's Ill ask, they got everything there.
Wierd thing is, none of my other 3 tanks have this problem, despite having the same water and light timing, One is planted though, and the other is barebottom.
thanks for all the input.
