Growth on screen is reducing every week and algae reverts to yellowish slime. This started after I increased lights (added one more bulb to previous 2 - so by 50%). I tried reducing time and took out aditional bulb. Nothing seems to help at all.
DT is clean and no sign of algae there. Corals seems to be happy too at the moment. I have only two small fish and feeding acordingly. I thing food amount that I feed is enough since corals grow like crazy. Actualy I'd like to slow them down as I will need to double tank size soon if this will continue at present amounts. :evil:
