We highly recommend viewing the CPR Aquatics CS Overflow video on the CPR Aquatics Web site for a general overview of all the CPR Aquatics overflows.

CPR Aquatics CS100 Siphon Overflow Features:

• Max. Flow Rate: 800 gph
• Outflow Size: 1" bulkhead
• Bulkhead Width: 10"
• Grated overflow
• Adjustable water level allows you to easily change the level in your tank
• Black top reduces algae growth
• Plastic screen helps to prevent fish loss
• Quiet operation

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 Aquatics Siphon Overflow 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.

Note: The Lid, not needed for operation, for the CS100 Siphon Overflow is sold separately.

Note: We highly recommend using the Aqua Lifter pump with your CPR Overflow to maintain siphon.
