DI Resin made to polish the product water coming from an RO ideal for Marine/Reef keepers. This 10 inch in line DI filter can add to any RO system. This cartridge is good for 1200 gallons of RO water and will reduce the TSD to 0 providing the TSD for the RO system is running less than 10 (in most cases this is the norm). The higher the TSD from your system the less life the DI cartridge will have. The unit comes complete with push fit connections. If this is an addition to your existing system you need to buy 2 X BRACKET-HOUSING-DI (you will find these in the Parts folder).
