CS Hang On Overflows

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.

Six Models are available

  • CS50: 300gph, one 3/4" Bulkhead

  • CS90: 600gph, one 1" Bulkhead

  • CS100: 800gph, one 1" Bulkhead
