Too much MH?

[Neptune777]

I have a 125 that I am thinking of lighting with 4 250w 10K Reeflux bulbs (currently have 2 running and 2 in the box). I will get a chiller to keep my temps stable.......so my question is this too much for this size system? I am and will be growing lots of SPS.....Experienced opinions needed! Thanks....

6 foot long right. If so 3X250w would work as well and be a little cooler. But if you want to run 4 go for it.

What is your tank length? I also have a 120 AGA I run 3 250 hqi pfo mini's and 4 t-5 blues. No dead light spots in my tank not sure it a 4th would be better or just over kill. If you do go with the fourth light please let me know how it works out for you, also the jump in your electric bill running the chiller and 4th light.

4 feet long, 24 inches tall....

For a 4 foot long tank, i'd look into maybe selling those and buying 2 400 watt fixtures. (800 watts).
You could probably get away with just running the 2 250 watters and be perfectly fine.
Either way, I wouldn't do 4 250 watters on a 4 foot tank. 3 even seems like too much IMO.
2 250 watters or 2 400 watters would be fine.

i agree with stewie

two 250 watt bulbs is what i would go with.

I have 2 250W de on my 120 and it is enough to keep any coral you are looking at. I keep acros on the bottom of the tank and they are fine.
