I have a 48x24x18 tank and was wondering if a dual 150w w/ dual 130w power compacts will enough ltg. to keep sps in upper half of the tank?

I would go 250s then you could keep anything, anywhere in the tank. The price difference isn't much either. 150s IMO should be saved for small, shallow frag tanks.

The only thing is I already have the fixture. I guess what I'm asking is will it work for now and if so how high off the water should I keep it?

Sorry to sound so pushy but some replies would be helpful because I'm looking to stock this thing asap. Already have lr and some fish but no corals.

Definatly go with 250's. IMO they will cover the 18" depth much better.

As long as the bulbs are not old then definitely put it to use. I would start with frogspawn/torch & a leather. Those should be ok lower in the tank. Then some inexpensive sps frags for the upper half. Don't spend alot. Start slow & you'll be ok.

I think it would work. I would suggest the 250 watt myself, but since you already have the fixture as you say, IMO, go with a 150 watt 10K bulb. Ushio makes a good one of those.

10K tends to be higher lumen output and higher PAR and will be a better bet for you if you do want to keep SPS. You will likely have to move your SPS higher up towards the surface of the water. The compact fluorescents will give you a nice balance if you go with an 03 blue 130 watt bulb.

Start it about 8 inches above the water, then raise it or lower it depending on the heat transfer that your tank can take and the growth you are seeing from your SPS.
