Best options for a quad bulb T5 assembly on a 55 gallon tank with no CO2?
I have a quad bulb, T5 assembly and J am not running CO2 in my tank. What would be the best options for my lighting? I want to keep this assembly for when I eventually upgrade to a larger tank and start using CO2, but for this moment in time which lights should I get, I need at least two bulbs since the power cords activate two bulb slots at a time. The fixture came with two T5 HO and two actenik, which are obviously worthless for me lol.
