Still eanring about LPS. Currently I only have a prata and a bubble and feeding them the green sugarcane liquid once a week and mysis directly twice a week, wonder if this too much? also got Suns in my tank..
not expert in this area but i used to keep them with 2x150 MH lamps in a 5ft tank. was with me for more than 1yr.
yr light is not sufficient for a clam, even if you put it high up
