4 Stage Value RO/DI System

BRS 4 Stage RODI Systems are perfect for reefers who have city 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. 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 Value 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

 

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

 

4 Stage Value 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 Premium 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 Deluxe 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.
7 Stage Pro RO/DI Systems – Perfect for almost any water condition, but if you have contaminants that use excessive amounts of DI resin, the 7 Stage RODI system is the ideal choice. It uses cation and anion single bed resins that give you added control and cost savings over traditionally used mixed bed resins. Most water supplies tend to exhaust either the positively or negatively charged resin more quickly than the other, and by separating the standard mixed bed resin into single beds, you are no longer throwing away good deionization resin.

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.
