I used CaribSea Ocean Direct Live Sand. I thoroughly washed it out until it was crystal clear. Made the mistake the first time not doing this with my 6 gallon. I also have 3 lava rocks & 2 pieces of coral. The lighting is LED. No hair algae on the rocks, sand or sides of tank. In my opinion this tank had done better than my first try. No filter only a little bit of air. Worse case I can take the fan coral out & clean it. I don't mind the way it is right now. I had some macro algae from petshrimp but took it out. I didn't feel the nutrient level was high and I wanted the algae that was growing to continue as food for the opae.
