RBTA Light Change

[collegeman]

I upgraded to 90 gallon aquarium from a 40 breeder and i now have a 36" nova extreme 4 bulb T5HO fixture. I was thinking about upgrading the light to a 48" 4 or 6 bulb T5HO but the RBTA seems very happy. It is actually of to the side of the aquarium where their is not much light. Should i upgrade the light or just switch the 36" bulb with higher quality bulb when time be?

If you aren't going to keep something that requires more light, why worry about it since the BTA seems fine.

Thanks, i guess i will stick with my current light. Anyone else have an opinion?
