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 375 LPD Premium RO/DI System, this system will deliver 1500LPD of product water by utilising 2 x 750 LPD 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.
