The AquaFX ASO Float Kit is a complete solution for automating the filling of your saltwater aquarium's top-off or water-changing reservoir. This kit works with your existing RO/DI system to automatically stop water production once your container is full, preventing costly and messy overflows. By adding this simple automation, you can produce pure RO/DI water with confidence, knowing the system will shut itself down safely and efficiently without your constant supervision.

This comprehensive kit includes all the essential components for a seamless installation. You will receive a 1/4 inch float valve, an Automatic Shut-Off (ASO) valve, a 1/4 inch check valve, and a one-foot section of 1/4 inch tubing. The float valve mounts inside your reservoir and rises with the water level, triggering the ASO valve to shut off the water supply to the RO/DI membrane, which also stops wastewater production, conserving water and prolonging the life of your system components.

This float kit is ideal for any aquarist who makes their own RO/DI water and wants to save time and eliminate the risk of accidental floods. It's a must-have upgrade for hobbyists who frequently fill large reservoirs for automatic top-off systems or for mixing large batches of saltwater. By automating the fill process, you can focus on other aspects of aquarium husbandry, secure in the knowledge that your water production is both reliable and safe.
