Lighting a 540 sps


New member
I will be starting a 540 gallon reef tank. I have a 72" outer orbit with 4 96 watt actinic 3 150 watt hqi MH. My tank is 96x36x36 What is everyones suggestion for add on lights. I would like to keep alot of SPS and some LPS. I would like any input on experiance with a 1000 watt MH from Aqua Medic? Please send advice.

You can probably get away with 400W MHs if you run something like an XM 10K bulb which has high PAR. Also, a good reflector, like the lumenarc 3 will help.
