Starting up a 125G tank. I need to find some 48" lighting. It can be pendants or a fixture. I want 250W MH's though.

I just went to a Mag 9.5 on my 125 gallon with a 55 gallon sump. It worked out just perfect for the proper turnover on my system.

Optimal sump turnover is between 3-5 times total system volume per hour. On a 125 gallon system with a 50 gallon sump, that is 175 gallons of water, minus rock, sand and corals. You typically take out 10-20% for rock, sand and corals, depending on how much you put in your system. At 10% off 175 gallons (158 gallons), you should be aiming for between 474 gallons/hour to 790 gallons per hour.
The mag 9.5 is rated at 975 gallons per hour pumping 0 feet up, 780 gallons per house at 1 foot, 740 gallons per hour at 3 feet, 685 gallons per hour at 5 feet, and 610 gallons per hour at 7 feet, and 450 gallons per hour at 10 feet. You are in a good range if you are pumping anywhere from 1 foot to 7 feet above it.
The mag 18 pumps at 1500 gallons per hour at 9 feet above it and still 875 pumping it 10 feet above it. Unless you are pumping the water over 10 feet above the sump, or have a tonne of elbows in your plumbing, the mag 18 will be too much pump.

I totally agree with this i thought the more flow the better thats y i went with 1600 gph for my 82 gallon, that was a huge mistake since you have to take into the account of the micro bubbles getting blown into the display and the constant splashing noise of water going into the comparments. i'm using a ehiem thats rated at 400-800 and have it at 600 gph probably to keep the micro bubbles from pouring into the tank lol. and the ehiem is super quiet :lol:

I had a RIO32HF prior to my Mag 9.5, and it was way over rated. This was one that was recommended to me by an LFS trying to make a few extra bucks rather than give me one that was property rated.
As riceboy pointed out, if you run a too powerfull of pump, you are more likely to get micro bubbles, and will have a lot louder splashing effect from your return. Also, my skimmer has worked a lot better since getting the lesser pump.

The Eheim 1262 is the pump I really wanted to get as well, but was in an emergency so went with the Mag 9.5 as that was what was available. Eheim are very highly rated and is what I would have got if I had the time. I am not at all dissapointed with my Mag 9.5 though.
