I have a Coralite 4' T5 (I think, it's the thin bulbs) and it doesn't get the edges enough. I have no idea what I want, I will take any suggestions. I don't really know what is out there as far as lighting goes. I was wondering what some of you more experienced fishkeepers would go with. I have no live plants, a Butti, some GTs, some clown loaches and some mbunas (that somehow all get along....for now anyway.) The tank is a 6' wide 150.
