I'm about to upgrade my lighting fromthe hood and bulbs that came with the tank. What is the rule on watts per gallon? I heard it's 10wpg, and I have a 55 gallon tank. Does that mean I need 550 watts per gallon? That's seems like a lot. Help!!!
to make it easy..if you have good lighting, you want about atleast 4 wpg to keep corals. but wpg is not the best way to measure. power compacts are good for your easier corals like leathers, polyps zoas and such. but for better corals you will need better lights like mh's.
