Increasing my lighting

[molybdenumman]

On my new 90g tank, I'll be able to use my existing 4X65W PC lighting system. Would it be beneficial to also use my old 2X55W PC lighting system in conjuction with the 4X65W? Would the added lighting be beneficial for my tank or is it just like peeing in the ocean?

Heck no, Dan! If you got it, use it. That's what, about 40% more wattage, more sheer PC lighting power? :biggrin:

I would definitely use it.

Me too, with one reservation. How old are the bulbs? If they're past their useful life, the degradation could cause algae problems.
