CPR CS Overflow Boxes Information



Part #: CS50

Feature(s):
  • For glass or acrylic aquariums up to 60 gal.
  • Flow rate 300 GPH.
  • 6.5" wide
  • 3/4" bulkhead outflow
A built in overflow is the most efficient method of draining aquarium water to a filter. If your aquarium does not have built-in overflow, CPR Continuous Siphon Overflows/Prefilters are the best means for getting water from an aquarium to a filter system without expensive modifications to the tank. They quietly skim up to six times more water than units with tubes.

The advantages of CPR Continuous Siphon Overflows/Prefilters include:
  • Adjustable water level allows you to easily change the level in your tank.
  • Black top reduces algae growth.
  • Quiet operation.
Tip: We recomond the use of an Aqua Lifter pump with the CPR overflows for trouble free operation. Another alternative is to hook the bleed hose from the overflow to the air intake of a power head. This way the overflow will continue to wok if it drawes some air into it or in the event of a power failure it will restart.

Hate!! Product Review by LARRY OSBORNE (Posted on 3/26/14)

Unsatisfactory

Comments: I hate this box and the tom's aqua lift. I will never buy another one that doesn't have U tubes in it. Put this CPR overflow box with toms aqua lift on my 125 gallon reef tank. When I set my two mp40's on in wave mode the movement of the water is to much for this style box. It's always getting air in it and stops the overflow. I took a double U tube box off a tank I'm not using tonight and now I can run my mp40s wide open without lose of suction. I give the CPR overflow box and toms aqua lift the worst two thumbs down I can. Don't buy either of these if you plan on upgrading to a wavemaker. Bty even without the wavemaker you still can't trust the toms aqua lift to not stop working while your away from home, so beware that you might come home to a wet floor one day.

Excellent!

Comments: I bought this overflow box because my cheap $40 one clogged and over flowed my tank. It was clogged with algae and I didn't notice until it was too late. I hated to spend the amount of money I had to for this, but when I received it, I was extremely pleased with it. It's thicker, and better built. I don't feel like its going to fall apart in my hands. And the noise reduction is amazing. I'm very pleased and recommend this product

Excellent!

Comments: Hook the siphon tube to a powerhead nearby in your tank and you'll constantly siphon all the bubbles out of the overflow box. Works great!!
