4 T5NO vs 2 T5HO
How would 4 T5NO compare to 2 T5HO on a 75gallon tank...I think it has been said the 2 HO would be high light, not sure about the NO's. (The NO's have individual polished reflectors) Lights will sit on the tank.
I would prefer medium light, and have the lights sit on the tank. I also have a single T8 strip with good reflector and was thinking 2 T5NO and the single T8 would be closer to med light and give a more even spread of light for the 18" front to back.
What do you guys think?
