**** Overflow Box Selection Chart ****


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.
* Plastic screen to prevent fish loss.
* Quiet operation.

  2. over rated gph? stay quiet once setup properly Review by Andy

    I have this overflow box paired with mag 12 pump(rated for 1200gph)initially & seems like it was way too much flow for the overflow box to handle. it had a lot of gurgling no matter how i adjust the vent tube. after i switched to a mag 9.5 (950gph), overflow box was able to quiet down significantly.

  3. A Good Product Review by JWW

    This is a good product for what it is. It handles what it is supposed to handle. I run a Mag24 through mine with no problem. The only drawback is having to use an airlift pump continuously to keep it running. (Posted on 5/26/2009)
