## Description

AQUARIUM/REEF  REVERSE OSMOSIS WATER FILTER SYSTEM WITH MANUAL FLUSH VALVEDI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero and is the last stage of an RO/DI unit. It is unnecessary to use the expensive proprietary DI cartridges that other RO manufacturers sell. Simply buy a refillable DI cartridge and fill with DI resin. You'll save money and get the same results. A constant supply of high purity water can be obtained by using two cartridges in series and allowing the first cartridge to completely depleted. During this operation, the second cartridge ensures that the water leaving the system is of the highest purity. New cartridges are placed into the polishing position and the remaining cartridge is put into the “roughing” position. This ensures complete utilization of all the exchange capacity, which lowers operating costs while increasing average quality.The clear cartridges are refillable, so you can save with buying media in bulk, and using the inline cartridges again, and again. 150 GALLON PER DAY SYSTEMS  (6 STAGE)1ST STAGE 5 MICRON SEDIMENT FILTER2ND STAGE 5 MICRON CARBON BLOCK WATER FILTER3RD STAGE 5 MICRON GAC WATER FILTER4TH STAGE 150 GPD MEMBRANE5TH STAGE COLOR CHANGING DI IN CLEAR REFILLABLE INLINE HOUSING6TH STAGE COLOR CHANGING DI IN CLEAR REFILLABLE INLINE HOUSINGCOMES WITH ONE CLEAR HOUSING PRE FILTER 1ST STAGE SEDIMENT.2 WHITE HOUSING1 AUTOMATIC SHUT OFF VALVE1 FILTER HOUSE WRENCHFEED WATER VALVEMANUAL FLUSH VALVEExported By ExportYourStore
