[spider8u]

Hi just wanted to ask what is the best food to feed my lps corals. And how many times a week i should feed them. Also when feeding them should i turn my power heads of and my skimmer. And is it best to target feed them or should put the food in the water. My lfs has DT's Live Marine Phytoplankton i was thinking about getting some of this would that be good for my lps corals thx
