Lifetime Warranty All Bulk Reef Supply RO/DI Systems are covered by our Limited Lifetime Warranty.


Bulk Reef Supply 6 Stage 75 GPD (gallon per day) 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.


6 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 & 6

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 checking your TDS meter.

6 Stage Value 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%

Product Questions

Is the tubing on the system 1/4" or 3/8"? Also how long are the tubing lengths that come with the system? Thanks.
Question by: John DiNovo on Sep 11, 2017 8:21:00 PM
All of our RODI systems include 10ft of ¼” blue, 10ft of black, and 10ft of red tubing.
Answer by: Charlie On (Admin) on Sep 13, 2017 2:37:00 PM
Is it ok to use a check valve on?
1 the drian line ?
2 after to ro membrane?
3 after the ro and di ?
And what psi to yours have to open
My Chinese bought ones are about 9psi?

Question by: troy long on Jun 5, 2017 6:19:00 PM
Our units come with an integrated check valve on the elbow for the product water from the membrane. While it isn't normally necessary to have a check valve on your waste light, there is no reason you couldn't. If you split your product water to go to multiple delivery areas, an extra check valve, such as one by a pressurized storage tank or holding tank, may be a good idea. While we don't have the exact psi rating on hand for our check valves, they are fairly easy to open and any residential water source will be capable of operating them properly.

Happy reefing!
