for a 55 gal tank (48 inch long), how much light is really needed for low light plants? we're gonna have eco complete on bottom. and would like a variety of different low light plants. Our current fixture is just a t8 fixture. I saw at home depot today, these bulbs called Glo, power glo (t8). they're suppose to be 18,000k. btw, our 55 gal tank, the ballast, only can have two 18 inch bulbs in it. So would two of those power glo's (18 inch) be enough?? If not, I know I'm gonna have to buy a t5 fixture, to just light some low light plants.
