do you think it would be enough for sps corals though? also i have a black limpet and was wondering if they are known to eat corals? hes been in qt tank for about a year. just because i could never see him in my 55. just curious because hes really neat looking and at least id be able to find him in a 10 gallon. if need be i can try to post a pic but im mostly computer illiterate and my wifes not home lol.

Thanks;
Trevor
