Makes up to 200 Gallons of RODI Water Per Day!
BRS 4 Stage Systems are perfect for reefers who have water treated with chlorine or relatively clean well water. Self-contained on a single bracket making them ideal for tight spaces or where a non-permanent connection may be required. Every BRS RODI system can be installed within minutes with the easy to use Mur-lok push-connect fittings that allow you to make leak-free connections. 
 
4 Stage Value Water Saver RO/DI Features:
Produce 0 TDS water
Minimal waste water
Multiple source 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.  The RO/DI units are designed 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 offer 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. Four stage RODI systems are a great solution if you only connect your RODI system temporarily or have little space to dedicate to storing a RODI system.
5 Stage RO/DI Systems - Our most popular systems handle common impurities found in 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 effectively treat any water your home may have prior to using it in your aquarium. 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 a true 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
Dual 100 GPD Dow Filmtec Membrane  (up to 98% rejection rate*)
1.5:1 Waste to Product Water Ratio
DOW is hands down the industry leader for residential RO membranes and when using two membranes, the output can be doubled without the need for any additional waste water over a single membrane. The 100 GPD Filmtec membrane can remove up to 98% of contaminants from traditional household drinking water. All membranes do require pressure to operate correctly, and DOW membranes in a water saver configuration require 65 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 will 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 it should be replaced.

4 Stage Value 200 GPD RO/DI System Recommended Conditions:
Minimum Water Pressure - 65 PSI
Max Water Pressure - 90 PSI
Recommended Water Temperature - 77°F
Recommended Max TDS - <500ppm
Waste to Product Water Ratio - 1.5:1
 
Water pressure can be increased by adding a booster pump before your RO/DI system. Low pressure may cause the RODI system to produce excessive waste water. Pressure over 90 PSI may cause damage to the RO/DI units filters and components.
 
*DOW Filmtec 100 GPD Membranes have a 96% - 98% typical stabilized salt rejection rate that can be reproduced through the following conditions;
Source Water Pressure - 50 PSI / Membrane (65 PSI for Water Saver systems)
Source Water Temperature - 77°F
Source Water TDS - 500ppm Softened Tap Water
Recovery - 15%
Minimum Salt Rejection - 96%
