Can you put 2 MH and 2 T5 HO over a 75g without a chiller and not have heat issues?

Possibly. Your chances would be better with no hood and a cool ambient room temp say maybe in a basement. I run a 120 with 2-250 halides in my basement and my heater does occasionally comes on. It greatly depends on how the lights are mounted.

they would be mounted on a hood. i have been debating on getting MH/T5HO or LED/T5HO just know that MH has some amazing growth and color for sps dom tank

I have 2 250 and two hydras over a rimless. No chiller, however if I keep the house at 76 or higher, the controller will start shutting down lights after about 6 or 7 hrs

jj70 and redwhiteandblue did you guys have a hood on those tanks or topless?

Mine is topless. I suspect if I had a hood my situation would be worse, although I think I could get by without a chiller by fans and adjusting run times

i have a 75 with 2X 175W MH and 2 T5s over it without a chiller. dont have a hood over mine and the tank temp stays constant at 79.5-80.5.

Not a quality fixture imo. Lots of ballast issues with those. But price is hard to beat
