how much lighting for my 30g .. would i need to keep hammerhead coral??
would 65 w be okay?? if not... would 130w be okay?? thanks for the help :happyfish
if you're talking about hammer coral i'd lean toward the 130Watts of PC. You might be able to get by if you place it at the top of the tank with 65W but i'd definately go with 130Watts.
HTH,
