lighting

[rmw4547]

Hi I have a 120 gal tank with two 150 hqi and two 96 watt actinics
the tank is a BB set up, my question is do I have enough light for my sps.

Montis on the top Id say.

Since a 120 is 24" in height it would have been better to have 250w MH. 150's will get you by so I agree with wentreefgirl and place them on the upper level of the rockwork. If you can try to save and upgrade the lighting because you have an ideal size tank for a reef IMO.

You should be able to keep them, but I wouldn't expect quick growth.

I used to keep a 3x150w HQI setup on my 155g tank and never had any problems keeping SPS, but once I upped it to 250s the growth increased quite a bit. I would stick with higher-output 150s if you want to try it, like 10k XMs or similar.
