T5 or Metal H. bulbs for my 90 gallon? HELP PLEASE

[gosupaintballe]

Ok i'm getting ready to set up my first saltwater aquarium ever and it's a 90 gallon tall, not long. I'm wanting to do some semi aggresive fish with a reef combo, but not sure what lighting i need to go with? Any suggestions? I dont wanna spend 500 bux or so on lighting and then later on find out i should of gotten something bigger and/or better then what i did get? Any help is GREATLY appreciated! Also, if i end up buying metal H bulbs do i have to buy a chiller also?

I'm not familiar with a "90 tall" but if the tank is taller than 20 inches, then a halide system is going to be what you want. T5s lack the penetration power needed for the really tall tanks.
You may need a chiller with this system because with a tall tank, you have less surface-area-to-tank-volume ratio, so less evaporation can take place, and evaporation is the key to keeping a tank cool without a chiller.
You can use T5s though if you plan to place your corals near the top of the tank and do not have anemones, which may move to the bottom where there would be insufficient lighting.

k thanks, i guess it's just a regular 90 gallon, i thought there might be a "tall" and a "long" 90? Maybe not? Anyone else got any input? I'd like to go with metal H. bulbs, but if i'm gonna have to buy a chiller too, that's gonna start running into some serious $ just for lighting purposes, as i've already spent a bunch on just the tank, stand, and all the filtration stuff i'm getting. Any more in-put is greatly appreciated people!

t5s (6 or 8 bulbs)work on a 90. sps work along with clams will be okay some of the acros that need the extreme high end of the amount of light would need mh to keep there color so as long as you are careful with your sps choices they work
