I am Really new to MH lighting. My two other tanks have T5 fixtures on them.

I Just got a 125 gallon 6 foot tank and am looking to get into MH lighting so i am able to keep SPS.

i know i dont want to go with one of the Nova fixtures.

they will be in the hood so i want to go with individual reflectors.

How many watts am i going to need?

Where is a good place buy them?

Thanks in advance Joe

I am setting up a 125 6' tank now. I am using 3 250w SE MH and 2 6' VHO with URL Super Actinic bulbs. I am not sure what the brand of reflectors are they were in the canopy when I bought the tank. All of my VHO pieces are coming from Marine Depot. Also there are always some good buys here on Reef Central.

I'm setting up a 125g and my lighting is as follows:

3- 12k Reeflux on 250w Dimmable Coralvue Ballasts and Lumenbright Mini Reflectors

2- 60" UV Super Actinic VHO on an Ice Cap 660

The MH's will be 16" from the bulb to the water and the VHO's will be 11" from the bulb to the water.

Talk to Mike @ RS....he gives great advice and support.

Not that there is anything wrong with using three 250watt lights. But I prefer the intensity of the 400watt lights instead. My set up consists of two 400watt 20,000k bulbs with a 4' flourecent for actinic light. With this configuration I get a little more wattage and alot more water penetration. My tank is bare bottom and I don't have the rock stacked very high, so most of my corals are at least 10" from the surface. Some are 15+" deep. So I wanted lights that would put out enough light to grow acros down near the bottom. And they do.

Just my 2 cents. Hope I could help.

i guess it would depend on the watts per square foot you would like to achieve. 3 lights will give you better coverage over 2. while the higher wattage can give more light penetration.

i would say 3 250's better than 2 400's and 3 400's is even better.
