    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

    100 GPD Dow Filmtec Membrane NSF Certified (up to 98% rejection rate*)

    3:1 Waste to Product Water Ratio

    DOW is hands down the industry leader for residential RO membranes. 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 require 50 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.

    • Minimum Water Pressure - 50 PSI
    • Max Water Pressure - 90 PSI
    • Recommended Water Temperature - 77°F
    • Recommended Max TDS - <500ppm
    • Waste to Product Water Ratio - 3:1

    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.
