fwp as in fresh water planted ?
planted vs not planted will make the difference in that decision,..for planted you need good PAR,..non planted and /or cichlid tanks you can pretty much use whatever you want. The fish dont care about the light
For planted,..id go with t5s.
There are 72" lights but i doubt youd need the whole length. Even a 48" should be good enough light to fill that FW tank. Oh,..i have one of those for sale
ATI powermodule,..but its way overkill for a fw tank
