AquaticLife & Aqueon light fixture question
I have a new 36g setup that I am trying to do a carpet in, so I have some higher lighting needs than I am used to. I replaced the original fixture with an Aqueon T5 Dual Lamp, each bulb is 6,700k and 18W. I was thinking this will not be enough, so I just went out and bought an AquaticLife dual T5 HO fixture 30''. The fresh water kind that has 1 6000k and 1 650nm lamp in it. (I don't know anything about HO lamps but I explained to the guy at the LFS what I was trying to do and he said this was the best one to get).
My question is do I need to use both fixtures? They don't totally fit, and looks kind of awkward with them stacked on the top of the tank, Even with the full glass versa-top. I don't know if the new aquaticlife one will be good enough alone. And does anyone know anything abiout these bulbs? 650nm? Thanks for your help in advance.
