  • The 4 Stage Reef Pure RO/DI systems are designed for Australian reefers who have tap water that is treated with chlorine, some chloramines and have minimal levels of other contaminants.

    All Reef Pure RO/DI systems feature full-sized DI resin stages for 0ppm TDS water and include a full set of filters with the system.

    4 stage systems are housed on a single bracket which makes them compact, easy to move and ideal if a non-permanent connection is required.

    Installing a 4 stage system is simple and can be done in minutes without any permanent modifications to your home or its plumbing.

    Please note: The system includes a 1/2" under sink adapter as standard.

    4 STAGE 100GPD Premium RO/DI SYSTEM FEATURES:
  • Easy to use and store
  • Full-sized DI resin stage for 0ppm TDS water
  • Colour coded ¼” tubing for simple identification
  • Common faucet adaptor included for hassle-free installation
  • Pre-installed NSF certified filters
  • 2 x 50 GPD Thin Film Composite (TFC) Membrane
  • Dual Inline TDS Monitor

  • Reef Pure RO Systems have designed RO/DI units with Australian reef aquariums in mind. However, the water that they produce is perfect for all other types of saltwater and freshwater aquariums.

    4 STAGES OF FILTRATION

    STAGE 1 – PUREPRO 5 MICRON SEDIMENT FILTER

    PurePro sediment filters remove sediment and debris that if allowed to pass through would clog carbon block filters and damage RO membranes.

    These filters have true step filtration integrated into their design. With 4 separate layers of micron filtration, the outside-in flow allows the outer layer to trap the larger micron particles with a much lower pressure drop.

    Step-by-step, trapping the larger particles layer-by-layer, allows these filters a much higher dirt holding capacity than standard spun polypropylene and string wound cartridges.

    STAGE 2 – PUREPRO 5 MICRON CARBON BLOCK

    PurePro carbon blocks are manufactured with high purity coconut shell activated carbon.

    With high performance, great dirt-holding capacity and the absence of carbon fines, they are perfect for use in reef aquarium RO/DI units, where high chlorine removal is needed.

    STAGE 3 – PUREPRO 50 GPD THIN FILM COMPOSITE (TFC) MEMBRANE

    Pure-Pro reverse osmosis membrane elements are one of the industry’s most reliable.

    Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that you can rely on.

    A high quality, thin film composite (TFC) membrane that processes 50 gallons per day.

    Just some of the water contaminants that these membranes will remove are lead, copper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium.

    PurePro membranes are rated at 50psi and will purify about 20% more water than competitive elements rated at 60psi.

    STAGE 4 – REEF GRADE MIXED BED COLOUR-CHANGING DEIONIZATION RESIN

    A mixed bed deionization resin is the final, polishing stage of the RO/DI system.

    It will remove any contaminants that may have passed through your sediment/carbon filters and RO membrane.

    This stage will achieve the 0 TDS RO water you need for a successful reef aquarium.

    The DI resin supplied by Reef Pure RO Systems is a mixed bed (both cation and anion) with colour changing indicator to let you know when it has become exhausted.

    The resin starts as a dark blue colour that will turn gold as it becomes exhausted. This gives you a very visual indicator, making sure you know when it is time for it to be replaced.

    4 STAGE 50GPD ESSENTIALS+ RO/DI SYSTEM RECOMMENDED CONDITIONS:
  • Minimum Water Pressure – 35psi
  • Max Water Pressure – 100psi
  • Max Water Operating Temperature – 45°C
  • Recommended Max TDS – <300ppm

  • If your home’s tap water pressure is below 35psi we strongly recommend the addition of a booster pump.

    All Reef Pure RO systems can have a pump added as an optional extra.

    Pressure below the minimum required 50psi will cause the slow production of product water, with excess production of wastewater.

    Whilst, pressure over 100psi may cause damage to the RO/DI system’s filters and other components.
