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 now feature a grated inlet instead of the fish screen previously included.

Great product and customer serviceAug 4, 2018

Great product and awesome flow rate. Handles just what it says it does as long as you use the correct diameter plumbing. FYI this one doesn't come with a lid so don't forget to order it if you prefer a lid. It also doesn't come with a pre filter and without it this is pretty noisy. What I did was cut a piece of sponge filter and stuck it in. Be sure not to wedge it in too much and don't cover the entire hole. I only did it to quiet it down.
Awesome customer service. They are very helpful and very prompt on getting back to you with any questions. They had my order ready and shipped super fast and I am well pleased with the whole staff. You will not be disappointed.
