I was wanting to know if anyone has used a hydroponics T5 fixture over their tank. I know most that I have looked at only have one cord to them for the 8 bulb setup so I was was thinking about maybe using two 4 bulb or even a 6 and a 2 bulb so I can kind of ramp up the lights over the tank without blasting at 100% full power once it turns on. I would love to get a ATI fixture but funds are on the low side right this second and later down the road I will upgrade. For the tank that it will be going over is a 90 gallon cube that is 30 inch wide 30 deep and 24 tall so I was thinking 8 to keep SPS but also to have good coverage front to back. Please share your thoughts or experiences if you have use them before.
