New set-up, need advice

[ReefOcean]

will 144 watts of t5 be alright? I understand that 54 watts of T5 give off 5000 lumens so a 6 bulb fixture will give off roughly 12k lumens and about 30 more efficient. Sigh, as soon as I think I have it figured out..hehe

I do like the idea though, I have problems controlling my temp with just LED over the tank. I might be adding 20 gallons with my new system, but I am starting to worry more and more about the heat of metal halides. I really thought it was negligible.

What would you suggest for bulbs ina 6 bulb fixtures? 4 10k and 2 actinics?
