Reef Pure Ro Systems Expert 6 Stage 400GPD (1500 litres per day)

Reefpure Ro Systems Expert 6 Stage 400GPD (1500 litres per day)

Need RO water in a hurry or just lots of it. The Expert RO unit will deliver it fast and with water saving too.

The 6 Stage 400GPD Expert RO/DI System is our flagship model. This system is designed for the serious Australian reefer or those with large aquariums needing larger volumes of RO/DI water for top off and water changes.

In addition to delivering all the features of the 6 Stage 100GPD Premium RO/DI System, this system will deliver 400GPD of product water by utilising 2 x 200GPD membranes and a high flow booster pump.

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 full-sized 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 which 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.

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.

PurePro 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.

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.

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.

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.

This system includes a high flow booster pump which will ensure that the optimal water pressures are supplied to the system.
