wow! thanks for the info beaslbob! I'm going back and forth with the sand vs. eco-complete! Ahhh! Decisions! The fact that sand is soooo much more cheap is swaying me towards it. I plan on getting an aquaclear filter that's rated 200 gph. So I would imagine that it along with some cory cats would help prevent algae build up on the sand. I like the idea of over filtering the water rather than under. But the set up you have is great!
