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 5 Stage Reef Pure RO/DI systems are designed for Australian reefers who have tap water that is treated with high amounts of chlorine and chloramines, along with common 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.

Our 5 stage systems are housed on 2 separate brackets, separating the single deionisation stage from the rest of the system. Installing this system is very simple but is better suited to a permanent installation due to the additional bracket.
