28 watt PC enough light for 10 gal nano


New member
Is 28 watts enough for a small 10 gallon nano reef tank. I was also wondering. My tank is 20inches long. Can I use a 24inch light with more power. I know It will over hang. Would that be a problem. I was wondering If also a 28 watts will be good for soft corals
It depends, if its 28 watts PC, yes it should be enough for some softies, shrooms and zoos, maybe not hough, only 2 watts per gallon, if its NO, i dont think anything can live under that, except for some shrooms.

Dont quote me on this, im not positive
