CPR CS150 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.
Specifications:
- Model: CS150
- Flow Rate: 1600gph
- Outflow Size: One 1-1/2" Bulkhead

Good Product
These are good over-flows. Like anything, you must maintain them. You must clean them and they will keep working. If you don't, expect problems somewhere in your system. <br>I appreciate that they are mostly quiet when adjusted correctly. Flow rates are as advertised.

Give it Time
I've had one of these purchased here at aquacave. little bulky due to design. its quieter than an eshopps (unmod'd). one little issue though. give it enough time when the lift/vacuum pump clogs, fails, etc., which it will, you will end up with your sump on your floor... 65 gallons of water when i went out for dinner, lots of flooring replaced that was already new. not happy. the more extras and parts = the more issues that can arise. tread carefully on this one, or any other cpr box.
