Im buying the lighting for my 90gal the tank is 26 inches tall i plan on keeping mostly LPS in the tank. As for the light i was thinking of going with a 4 buld VHO setup with a icecap ballast this would be the cheapest setup for me and i believe this would be plenty of light for what i wanna keep or at least i think it would be. My other option was i would have to get 2 ice cap ballasts and run 6 T-5s over the tank this would cost me a bit more. Is there any major advantage to the t-5s over the VHOs. I know the VHOs will produce alot more heat but i will just put a canopy fan on and the room is air conditioned in the summer.
