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

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.

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.

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 - <300ppm

Water pressure can be increased by adding a booster pump before your RO/DI system if a pressure increase is required. Low pressure will cause slow production of product water, with excess production of waste water. Pressure over 90 PSI may cause damage to the RO/DI units filters and components.

*DOW Filmtec 75 GPD Membranes have a 96% - 99% typical stabilized salt rejection rate that can be reproduced through the following conditions;

• Source Water Pressure - 50 PSI / Membrane
• Source Water Temperature - 77°F
• Source Water TDS - 250ppm Softened Tap Water
• Recovery - 15%
• Minimum Salt Rejection - 96%
