 Re: how long should i keep my lights on
light's, let me get to the first part. you shouldn't have anenome's under pc's in first place. they need considerably more light than that. and becareful you didnt get a condie's they will kill your fish and any coral's they touch. amount of light time is based on type of light's and what you have living in your tank. and you dont need to have antic's come on 2 hr's before sunlight bulb's. it wont hurt nothing, but it is electric and heat. mine come on a 1\2 before second stage bulb's. i myself am running 3 set's of t5's and have them all staged a half hour apart |
