I have a Coralife Turbo-Twist x6 sterilizer and I want to get about 200GPH for the best effectiveness that I can get I have the sterilizer mounted below the tank on the top of the stand. I am putting the pump directly in the tank on the back wall and plumbing over the side and back up to the tank to the return. So I think total height change about 3 feet. What can i use for a powerhead or pump that is small size and reliable for this application?

Thanks in advance,
Either the Maxi-Jet 1200 or Penguin 1140 would give you around 150-200 GPH with a 3 ft head. Both are very reliable IME and don't take up a lot of room in the tank.

I assume you don't have a sump to place it in.
You could just T off the return pump to the Coralife Turbo-Twist and restrict the flow to the UV using ball valves. Your Mag 12 should provide plenty of power to do that.
