CS50 Overflow Box (300 gph) – CPR Aquatics

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 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 include:

* Adjustable water level allows you to
easily change the level in your tank.
* Black top reduces algae growth.
* Quiet operation.
* CS Overflows feature a grated inlet.
