Have had a colony for about three weeks now and they look as though they are breaking off in clumps. Now I only have T5 lights with one day and one atinic and I am guessing that this isn't enough light. (Lfs said it would be but I am guessing not) I have ordered a new light setup that is coming monday. My params are all good, Nitrite-0, Nitrate-o-20, Alk-8 Amo-0, Ph-8 and salinity-1.025, two pwerheads in a 75 gallon. Don't have a test kit yet for calcium or phosphate yet but do have a phos sorb pad in the filter as well. My coral banded shrimp likes to climb on them and dig his little claws down into the polyps. Could he be my problem?
