UV Sterilizer and Tubing/Plumbing Quandry *PIC*

I'm planning on installing a DoubleHelix UV sterilizer on my 75 gallon tank, which has a height of 21 inches. The idea is to mount the sterilizer to the tank stand, and pump to it with a pump/powerhead mounted inside the tank.

According to CustomSeaLife, I need 100-200gph at the inlet of the sterilizer. Given that the sterilizer will be mounted 21 inches from the top of the tank, and the pump will be down in the tank about 12 inches from the top, I'm estimating 3 feet of distance between the pump and the sterilizer intake, so I'm considering a Rio 600 pump.

Another factor is going up the tank then down the back, and if I use elbows I further reduce the pressure, so I'm thinking a u-tube would alleviate that. Unfortunately, I can only find 3/4 inch u-tubes, where the fittings on the sterilizer is 1/2 inch. While I could adapt to fit the 3/4 inch u-tubes, I would prefer a cleaner look. I've considered elbows, but that means adding adding 4 elbows for to and from plumbing, which will definitely impede flow.

I'm also a bit concerned about the pump itself, which might not have any power left to force water back into the tank, given the 3 feet TO the pump, 3 feet INSIDE the pump, and 2 feet BACK UP to the tank.

Anybody got any ideas? Anybody got any other suggestions?

Thanks for ANY input.
