Reef Pure RO 6 Stage 100GDP Premium + RODI System

Our ‘Premium’ range of RO/DI systems, across all stage variations, include all optional accessories as well as 2 x 50GPD RO membranes. These systems do require a minimum water pressure of 65psi.

So, as long as the minimum water pressure can be provided, they will produce water twice as fast as a single standard 50 GPD membrane whilst cutting the amount of wastewater in half. If your home’s water pressure doesn’t reach the minimum 65psi required, don’t worry, you can add a booster which is sold separately.

The 6 Stage Reef Pure RO/DI systems are designed for Australian reefers who have tap water that is treated with high amounts of chlorine, chloramine and high levels of many other contaminants, such as heavy metals and nutrients.

All Reef Pure RO/DI systems feature high-quality, Mixed Bed Colour Changing DI Resin stages for 0ppm TDS water and include a full set of filters with the system.

If you are looking for total peace of mind and are simply unsure of what is in your tap water and don’t want to take the risk, then one of our 6 stage systems are for you. With most Australian households having tap water that contains excessive TDS levels and difficult to remove contaminants like chloramines, phosphates, nitrates, silicates, the additional carbon stage and DI resin stage is a must to remove these pollutants.

The 6 stage systems are housed on 2 separate brackets, separating the dual deionisation stage from the rest of the system. Installing this system is very simple but they are better suited to a permanent installation due to the additional bracket.

6 Stage 100GPD Premium RO/DI System Features:

  • Easy to use and store

  • Dual, full-sized DI resin stages for 0ppm TDS water

  • Colour coded ¼” tubing for simple identification

  • Common under-sink tap adaptor included for hassle-free installation

  • Pre-installed NSF certified filters

  • Dual carbon stages for superior chlorine & chloramine removal

  • 2 x 50 GPD Thin Film Composite (TFC) Membrane

  • Dual deionisation stages for unmatched water purity

  • Pressure Gauge

  • Dual Inline TDS Monitor

  • 100 GPD Premium Upgrade Kit

Reef Pure RO Systems have designed all of our 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.

Included Accessories:

  • 2 Meters RO Tube in Yellow (Production Water), Red (Waste Water) & White (Source Water)

  • 1/2″ BSP to 1/4 RO Tube Undersink Connector (measures approx. 19mm)

  • Drain Clamp (For Wastewater Line)

  • Housing Wrench

  • All Prefilters, RO Membrane & DI Resin


STAGE 1 – 5 Micron Sediment Filter

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 – 5 Micron Granular Activated Carbon

Granular activated carbon cartridges are highly effective at removing high levels of chlorine and chloramines. They are also highly effective at removing volatile organic compounds such as benzene, trichloroethylene and other petroleum-based contaminants.

Stage 3 – 5 Micron Carbon Block

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 4 – 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 5 & 6 – 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.

6 Stage 100GPD Premium RO/DI System Recommended Conditions:

  • Minimum Water Pressure – 65psi

  • Max Water Pressure – 100psi

  • Max Water Operating Temperature – 45°C

  • Recommended Max TDS – <300ppm

If your home’s tap water pressure is below 65psi, you will need to add a  booster pump to this system. All Reef Pure RO systems can have a pump added as an optional extra.

Pressure below the minimum required 65psi 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.


  • Swallowing may lead to serious or fatal injury in as little as 2 hours, due to chemical burns and potential perforation of the esophagus.

  • Never allow children to replace button batteries of any device.

  • If you suspect your child has swallowed or inserted a button battery immediately call the 24-hour Poisons Information Centre on 13 11 26 for fast, expert advice.

  • Regularly examine devices and make sure the battery compartment is correctly secured, e.g. that the screw or other mechanical fastener is tightened. Do not use if the battery compartment is not secure.

  • Dispose of used button batteries immediately and safely out of the reach of children. A battery can still be dangerous even when it can no longer operate the device.

  • Tell others about the risk associated with button batteries and how to keep their children safe.
