CPR CS90 Aquarium Overflow Box

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. 
  • CS Overflows feature a grated inlet.

  • Model: CS90
  • Flow Rate: 600gph

  • (1) Vent tube with small “O” ring
  • (1) Bulkhead assembly
