I posted this in the sps forum too but any advice will help. I have always used halides so I am new to the T5 world.

Tank is 263 gallons (60L x 39W x 26H). Right now I have 9 T5s 60" (80W ea.) running on 3 Icecap 660 Ballasts over the tank, plus a single MH 250W 12K reeflux. The T5 are in order from back to front:

ATI Blue Plus
ATI Blue Plus
ATI Aquablue Special
ATI Blue Plus
Fiji Purple
ATI Blue Plus
250w MH
Fiji Purple
ATI Aquablue Special
ATI Blue Plus

The halide is giving off way too much heat. Can I keep sps with just the 9 T5s? Would you recommend a different layout/assortment of T5s?

They are 12" above the water level so a total of 38" to the bottom.

Thanks for your input.

t5 will grow sps just fine, they will more than likley have to be lowered from 12" though. The average height of t5 off the water is 5-7".

also you have 720w of T5. they are producing more heat and using more energy than 250wx2 halides and with the right reflectors will cover 5ft easily. You just dont feel the heat because its spread over the length of the bulb. Kind of counterproductive to switch to T5 and use 720w worth if the goal is reduced heat and efficiency IMO. but yeah thats plenty of light without the halide.
