Yep, I got a 1600 gph pump, and I think it will work fine. I also got my quad T5 fixture w/ 2 veg 2 bloom bulbs. I'm just waiting and hoping it all arrives in one piece.

I'm still trying to find a way of putting on a filter though. I bought some mesh filter inserts but their to big for the 1/2 in pipe. Is a filter really needed, and doesn't the pump have one? (mine is submersible)
