This basket type wastewater bar screen can be used as a permanent or temporary solution to remove waste water from the bottom of your aquarium. The basket will hold the waste water until it is removed from the tank. This can be done manually by removing the basket from the tank and clearing out the waste water or automatically via an automatic siphon system which creates suction through the screen and into a container. The screen itself is made of high quality stainless steel mesh providing excellent visibility and filtration without adding any bulk to the aquarium. The screen comes complete with a drain plug so you can easily access the waste water if needed.
