  • Quick Overview

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. 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: All units except the CS150 come with slip screen, sponge and vent tube to help reduce noise.

All Units come with the Aqualifter Pump and acrylic lid for quieter operation.
