I'm back to be indescisive once more, lol, don't shoot me. would 2pg be okay without Co2?(I'm trying to penny pinch a little bit on this tank, but if it comes right down to it i'll buy any other hagen system)
I'm looking at the 30in. ( 2 - 24" 20w lights) the same light I was looking at, just for 20long size.

I decided that since it's mainly shrimp, I'll get more floor space(my bamboo shrimp only climb somewhat and my vampire very little.) and do a 20g l., the light's only about 1$ more anyways.
edit: oh and dunga, how in the world do you keep cabomba in low light? I have some in my other tank(3.25 wpg) and anything thats not directly in bright light turns yellowish.
