Retrofit Overflow RSS18

Description

The CPR Aquatic Retrofit Overflow RSS18 is a simple way to add a surface skimmer to a tank with a drilled overflow in the back of the tank. It's also a great way to keep the water level constant in your saltwater aquarium, and it will increase the rate at which surface water, and the film and dust with it, is removed from the aquarium. This is a open-back model. The walls of the RSS overflow can be attached to the back wall of the aquarium with silicone. The fully routed grates are closed off on top for increased grate support. Dimensions: 12.5" Long x 4" Wide x 5.25" High.
