I have two 175w mh lights and was wondering if it would be enough to keep some high light corals or if I need to go with the 250w mh. I have a 75 gallon aquarium that is 20" deep. Thank you in advance for any help.
From what I have read on reef central this should be plenty of light. The higher light corals might be better if put a little higher in the tank, but I do believe this would be enough light to keep high light corals.
