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 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.


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

75 GPD Dow Filmtec Membrane NSF Certified (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 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 depleted and is a good indicator to let you know when to start looking at your TDS meter.

5 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%

  • Long lasting and easy installation By richard on 10/16/2017

    I got this in 2011 not one single issue with this unit at all still going strong and filters are very easy to replace
  • Very impressive unit By MarkS on 9/13/2017

    I just received mine last week and was totally impressed at the quality of the product....its SOLID, very nicely built and works perfectly. One recommendation....although multiple water connectors are provided with the product, I would highly recommend going out and purchasing a "SharkBite1/2 in. Push-to-Connect x 1/2 in. Push-to-Connect x 1/4 in. Compression Service Stop Tee" if you have PEX plumbing in your house. It's very easy to install (no tools other than a pex cutter) and is the recommended way to connect to PEX. Saddle valves which are provided are notorious for leaking and not recommended for PEX.
  • Great product By 210 tank on 9/8/2017

    Bought this unit to do water changes in my 210 freashwater tank. Works great.
  • Great long lasting By Bakerrichard27 on 9/1/2017

    I got my unit I'm 2011 still works flawlessly and installation was a breeze
  • Works really well By BRIAN on 7/10/2017

    Works really well. Overall happy with it. Comes with all kinds of different fittings to attach it to almost anything.

    One problem I had, was the red push connection coming off the horizontal canister was leaking, also where the same hose connects to the small box. I just cut a longer portion of hose off another crappy rodi I had and put it in. No more leak.

Product Questions

If I have a whole house carbon filter, do I still need to have a carbon filter as part of the RO/DI system?
Question by: Ken O on Jun 3, 2017 7:55:00 PM
So long as your carbon block is completely removing chlorine and/or chloramine from your tap water, you may not need the extra carbon block, but as this is critical for protecting the membrane from these harsh disinfectants, it may not be a bad bit of insurance.

Have a great day!
