It's a 29gal Via Aqua..that's been gutted (thanks LFS guys for all that great advice...this was befor I knew what RC was). Currently the lighting over the tank is 5X24W TEK T5 retros with the sixth bulb over the HOB fuge. If I add the 50-60gal sump/proptank that I've been thinking aobut soon I may put the 250w MH I originally bought for the tank over it, at least durring the winter...Or sell the 250 and put a 150de like you have on yours and go year round with it...but I'm getting pretty good results with the T-5's right now so I'm not sure if I want to switch.... I've been thinking about using a doseing pump (which reminds be to go to our instrument graveyard and to look for a useable pump)..Right now I'm adding 90-100mL of each of my DIY 2-part, and it's causing me to battle pH (which I'm hopeing a dosing pump will solve)
