enough light for SPS?

[i2ik]

Hi guys! i have been thinking about my lights over the past few weeks. i presently have a 33G and 4xT5 (50/50) and i am trying to keep my first SPS which is a brown montipora. He is at the top of my tank and doesnt look really good. Maybe i dont have enough lights...(3 inch under the water, so still very close to the lights)

I will finally get a new tank in 2 months. its going to be a 90G (36x32x20) and i was wondering if 8xT5 should be enough to keep SPS. I dont wanna go for MH because its getting too hot in my room. And what combinaison should a go with? (how many artinic, how many white bulb) for the best result.
Thanks a lot
Richard

I know several people wjo have kept SPS under just VHOs 440 or more watts and eventually upgraded to MHs in the end. Is it possible? Yes but they wont do as good as under MHs
I also know people who have kept derasa clams under VHO it had only grown 3/4 of an inch in 2 years. Now in my tank it has grown 1/4 inch in less then 3 months under MHs
Just food for thought here

I am having a MH on my other tank (27G). The problem is that its producing too much heat and my tank is in my room. After the day, its get to about 26degree cielsius in my room. Even with some ventilation, i dont think that its going to change anything.

What do you guys think?

Buy a small AC for your room

Many people keep certain SPS (green slimer always a good choice) under VHO or T5's. I got a frag from a reefer of a nice looking blue acro he grew under VHO, in my tank under a 175 halide and a 55 watt PC actinic it turned brown.

The montipora should be fine. MattM posted pics awhile back of a Monitpora capricornis that was grown from a frag in no time under 32 watt PC's.

I would look into possible CA/ALK problems, or P04 which is detrimental to SPS.

During summer the AC from the house should do fine, if not, i will keep my door open :roll:
