CPR CS90 DELUXE Aquarium Overflow Box

**** Overflow Box Selection Chart ****


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.
* Plastic screen to prevent fish loss.
* Quiet operation.

    Very quite and low profile

    The overflow box is awesome except for a couple of flaws, that's why I gave it 4 stars. #1 the lid doesn't fit securely on top of the box, it kinda hangs off the side. #2 it took too long to find the sweet spot for the vent tube with the rubber ring, other than that I would recommend this product.

    The CPR overflow has to be the best overflow box you will ever use. You simply cannot go wrong with this product.

    i like it and easy to set up

    i'm the first to review? really?! i'm surprised more people aren't purchasing this product as i'm very satisfied with it. obviously not able to drill my tank and this was great especially with the back up pump system! the concern is that most siphon systems could fail with air bubble accumulation however this potentially is comletely eliminated. just used some PVC cement and primer when connecting the drain hose, allowed to dry for 24 hrs, no leaks. very quiet. does make some noise, obviously, but sounds like a gentle stream or water fall. small thin tube with o ring easy to move up and down to noise comfort level. make sure to match pump return gph to what your overflow system can handle. also able to adjust water level in tank up and down with the 2 simple screws on top for optimal levels.
