oh my well on a 25 gallon you might want to look into a 4 bulb t5 setup or a led so you can grow pretty much anything you want
as for the power heads a mp10 would work great in there
i was gonna do one bulb because the fixture i already have has only one place for a bulb, all i really want to grow are palys, zoas, and other soft corals. would that work?
that mp10 is a llittle out of my price range... what koralia should i use lol ;D
Prob not for lighting..
look on ebay for a cheap led unit
or again i would go with a 4 bulb system if u cant afford a led unit
