i can't imagine keeping a reef tank without sand, and I like all the critters that live and play in it. I have had sand in my 20L for a couple of years now and I don't have algae problems. Snails and water changes are our friends!
I am curious about your flow changes as well. Do you shoot the pumps at the rocks just below the corals, at the corals, or at the glass?
