![]() Hi all,
I'm looking at changing my lighting from PC to metal halide. Currently I have 2X55W PC and 2X30W NO actinic. I've found a 400W MH ballast only(not wired/no box) for $80 from a hydroponics shop. I'm woundering if a 400W MH would be too much for my tank? My tank is 54 gallons(18" deep, 20" high, 36" wide). Any comments on buying ballast's from a hydroponics shops? |
