i dont think you can really get by with just those bulbs you can buy at petco. i use 2 of those over a 20 planted and they just barely allow my plants to grow. maybe if you keep only low light corals at the very surface...but that would be awkward.
the best lighting for my system?
hi, i currently have HO fluorescents: 15" reef sun, 18" 50/50 and a 18" actinic in my 25 gallon tank with corals and fish. i dont know whether the lights are quite bright enough, the corals seem to be ok- although sometimes they don't come out, what do you think? is the lighting up to scratch?
