    BRS 5 Stage Systems are our most popular systems and are great for a majority of wells, along with city water that is treated with chlorine, or small amounts of chloramines. The single Color Changing DI stage comes on its own bracket allowing you to customize the installation depending on the space you have available. 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. 


    PLUS RO/DI System Included Upgrades

    • HM Digital Inline Dual TDS Meter - Instantly know the purity of your water, before and after the deionization stage. The inline probes come pre-installed and with the simple push of a button, your waters TDS is displayed on the LDC monitor. 
    • Glycerin Filled Pressure Gauge - Reverse Osmosis membranes require a particular amount of pressure to operate efficiently, and using a pressure gauge will help ensure your system is performing correctly. Pressure Gauges also work as a great indicator of when sediment or carbon blocks start to become clogged. 
    • Membrane Flush Valve - Keep your RODI system running like new by flushing the membrane for a few minutes before and after each use. Membrane flushing helps remove any built-up mineral deposits from your membrane, that could harm performance, or even cause a complete clog.

    Lifetime Warranty 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 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.


    5 Stages of Filtration

    Stage 1

    GE ROSave.Z 1 Micron Depth Sediment Filter NSF Certified

    Made in the USA and made for Reverse Osmosis applications and will last up to twice as long as other conventional depth sediment filters. The longer lasting filters help protect the more expensive carbon blocks allowing you to save money.

    Stage 2 & 3

    BRS 1 Micron Universal Carbon Block NSF Certified (Chlorine 35,000@1 GPM / Chloramines 3,500@0.5 GPM)

    Our Universal Carbon Blocks are manufactured with high-quality catalytic active carbon that is then extruded with up to 30% more carbon than standard carbon blocks. These blocks are excellent at removing VOC, chlorine, and chloramines.

    Stage 4

    Dual 75 GPD Dow Filmtec Membrane NSF Certified (up to 99% 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 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 membranes in a water saver configuration require 65 PSI of feed pressure to operate efficiently.

    Stage 5

    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.

    5 Stage Value Plus 150 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 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 (65 PSI for Water Saver systems)
    • Source Water Temperature - 77°F
    • Source Water TDS - 250ppm Softened Tap Water
    • Recovery - 15%
    • Minimum Salt Rejection - 96%

    Can you use this for fresh water aquarium?
    Question by: Roberto on Dec 31, 2023, 10:06 AM
    Hey there, Yes you can use this for freshwater you would just need to re-mineralize the water. Thanks!

    Does this already have a check valve built in for a auto shut off float or do I need to buy one as well
    Question by: Jake Roerig on May 26, 2022, 11:54 AM
    Hey there,
    Thank you for reaching out to us. This does not have a check valve built in.

    Please let me know if you need anything further and take care!
    Answer by: Matt Lucero (BRS Staff) on May 26, 2022, 3:12 PM
    where is the auto shut off valve and how does it work?
    Question by: joe on Dec 14, 2021, 12:11 PM
    Thank you for reaching out. The Auto Shut Off valve is installed on the top of the RO unit by the RO Membrane. It is connected to the source water line and the product water line. When pressure builds on the product water line due to a closed valve, it pushes a diaphragm in the switch that causes it to turn off the source water. Here is a link with instructions and photos of the valve:
