The AquaFX Float Valve with Wing Nut 3/8 is an American-made, adjustable float valve designed to provide automatic water level control for your saltwater aquarium's RO/DI system. It works by shutting off the water flow once a desired level is reached in a container, such as an automatic top-off reservoir or a water mixing station. This essential component seamlessly compliments the AquaFX Automatic Shut Off (ASO) kit, ensuring efficient and reliable operation of your water purification setup.

This robust float valve features an adjustable wing nut, allowing users to precisely raise or lower the water level inside the tank or container to meet specific needs. The wing nut itself is crafted from NSF approved PVC, while the accompanying hardware is made from durable 18-8 stainless steel for long-lasting performance in aquatic environments. It is equipped with a compression 3/8 inch tubing connection and offers versatile installation, capable of being mounted on either the side or the top of your chosen container. Please note that the AquaFX ASO-kit must be used in conjunction with this float valve to properly shut off RO/DI system wastewater.

This product is an ideal solution for reef aquarists seeking to automate and simplify their daily water management tasks. It is perfect for those setting up an automatic top-off system to compensate for evaporation or for anyone building a dedicated RO/DI water mixing station for regular water changes. By ensuring consistent water levels and preventing overflows or dry-outs, the AquaFX Float Valve helps maintain stable water parameters, reduces manual effort, and provides peace of mind for a healthier, more stable reef environment.
