AquaFXEasily convert any 3-stage reverse osmosis unit into a 4-stage RO/DI unit! AquaFX Add-On Deionization (DI) Filter installs last in line of your existing reverse osmosis (RO) unit to remove additional contaminants and dissolved solids. Color changing DI resin slowly turns rust red/orange when exhausted or at the end of its useful life for simple visual confirmation of filter performance.

AquaFX Add-On Deionization (DI) Filter is perfect for aquarium applications requiring pure water free of contaminants and dissolved solids. Use pure RO/DI water to mix synthetic salts for marine reef aquariums housing corals, anemones or other sensitive aquarium inhabitants. For applications demanding 18 megohm (ultra pure) water, the use of two DI units is strongly recommended. AquaFX Add-On Deionization (DI) Filter measures 4-1/2" dia x 11-1/2" high. Made in the USA.
