BRS 4 Stage Systems are perfect for reefers who have water treated with chlorine or relatively clean well water. The 4 stage systems are self-contained on a single bracket making them ideal for tight spaces or where a non-permanent connection may be required. Installing a RO/DI system only takes a few minutes and can be done very easily without any permanent modifications to your home or the plumbing. 4 Stage Plus RO/DI Features: Dual TDS Meter Glycerin Filled Pressure Gauge Pre-installed Automatic shut-off valve Pre-installed Flush Kit Multiple source water connections Drain/waste water connections Mur-lok Push Connect dual EPDM O-Ring fittings 10 Ft Each of 1/4" Blue, Red and Black Tubing Pre-installed NSF Certified Filters All Bulk Reef Supply RO/DI Systems are covered by our Limited Lifetime Warranty. Bulk Reef Supply RO/DI systems only use the latest filters and components in Reverse Osmosis technology. We have designed our RO/DI units especially for reef tanks, but they can produce perfect water for other types of saltwater and freshwater aquariums too. If you have a well, or you are connected to city water we provide a variety of RO/DI systems that will fit your aquarium's needs. 4 Stage RO/DI Systems - Perfect for city water that is treated with low amounts of chlorine, or well water with very minimal contaminants.5 Stage RO/DI Systems - Our most popular system handles most types of well water along with most types of city water treated with chlorine including small amounts of chloramines.6 Stage RO/DI Systems - If you are not sure what is in your water, or it contains excessive amounts of TDS or hard to remove contaminants like chloramines, phosphates, nitrates, silicates, etc. The BRS 6 Stage systems are designed to treat any water your home may have effectively. The Dual DI stage helps with the hard to remove ions like ammonia, phosphates, silicates, etc. 4 Stages of Filtration Stage 1 Purtrex 5 Micron Depth Sediment Filter Sediment filters trap debris and other free-floating particles that would normally clog expensive carbon blocks and foul membranes. Purtrex filters are an actual depth filter with a graded density that progressively gets tighter through as water passes through the filter allowing them to last longer than the competitors. Stage 2 BRS 5 Micron VOC Block (Chlorine 15,000 @ 1 GPM) Our VOC carbon blocks are specially formulated to remove and reduce chlorine and volatile organic compounds from household water. Stage 3 75 GPD Dow Filmtec Membrane (up to 99% rejection rate*) DOW is hands down the industry leader for residential RO membranes. The 75 GPD Filmtec membrane can remove up to 99% of contaminants from traditional household drinking water. All membranes do require pressure to operate correctly, and DOW's membrane only requires 50 PSI of feed pressure to operate efficiently.For more info on DOW membranes - Click Here Stage 4 Nuclear Grade Color-Changing Deionization Resin Deionization resin is the final stage of the RODI system and can polish your water down to 0 TDS. The DI resin is a mixed bed with a color changing indicator to let you know when it is becoming depleted. The resin starts as a dark blue color that will turn gold when as it becomes exhausted and is a good indicator to let you know when to start looking at your TDS meter.For more info on Color Changing DI Resin - Click Here Need Replacement Filters? 4 Stage Chlorine/VOC Filter Kit BRS RO/DI 4 Stage System Comparison BRS 4 Value RO/DI Systems BRS 4 Value Plus RO/DI Systems Gallons Per Day 75, 100, 150, or 200 75, 100, 150, or 200 Sediment Filter Purtrex 5 Micron Depth Sediment Filter Purtrex 5 Micron Depth Sediment Filter Carbon Block BRS VOC 5 Micron Carbon Block BRS VOC 5 Micron Carbon Block Membrane 75 or 100 GPD Dow Filmtec Membrane 75 or 100 GPD Dow Filmtec Membrane Deionization Single Mixed Bed DI Stage with Refillable Cartridge Single Mixed Bed DI Stage with Refillable Cartridge Auto Shut Off Valve ✓ ✓ Canister Wrench ✓ ✓ Laundry Tub Connection Adapter ✓ ✓ Chrome Faucet Diverter Valve ✓ ✓ Glycerin Filled Pressure Gauge ✓ Flush Kit ✓ Dual Inline TDS Meter ✓ Dimensions 16" x 6.25" x 15.5" 16" x 7" x 15.5" 4 Stage Plus RO/DI System Recommended Conditions: Minimum Water Pressure - 50 PSI Max Water Pressure - 90 PSI Recommended Water Temperature - 77°F Recommended Max TDS -
