System Stages 1 System Stages

4 Stage RO/DI System

The base 4 stages utilised in all Reef Pure RO/DI Systems.

Stage 1 – Sediment Filter
Sediment filters remove sediment and debris that if allowed to pass through would clog other filter stages and damage RO membranes.

Stage 2 - Carbon Block Filter
Our carbon filters are manufactured with high purity coconut shell activated carbon. They rapidly remove toxic compounds from tap water, primarily chlorine and chloramines. This ensures the system's RO membrane and your reef aquarium are protected from these toxic substances.

Stage 3 – 50 Gallon Per Day Thin Film Composite (TFC) Membrane
At the core of the RO/DI system is the RO or Reverse Osmosis Membrane which removes the majority of impurities from your tap water. After this stage, the water is about 98% pure, but in order to be safe for a reef aquarium, we need water which is 100% pure, or as close to as is possible.

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 filter, carbon filters and RO membrane. This stage will achieve the 0 ppm TDS RO/DI water you need for a successful reef aquarium.

5 Stage RO/DI System

The 5 Stage RO/DI System adds an additional granular activated carbon filter between stages 1 and 2. This is vital for the filtration of water supplies which may be treated by your local water supplier with chloramines. Chloramine is a disinfectant which is much more difficult for a single carbon stage to remove when compared to chlorine. In order to find out what your water supply is using you can reach out to your local water provider and ask for an Annual Water Quality Report. You can also check their website for a downloadable copy. This will show the Total Chlorine and Free Chlorine in your water supply. If the reported Total Chlorine is significantly more than the Free Chlorine, this indicates that your water supplier is using chloramines as a disinfectant and a fifth stage will be required. Some water suppliers will report chloramine as a separate parameter and this makes identifying this issue much simpler.

Additionally, a carbon filters ability to absorb large volumes of chloramine and chlorine will degrade over hours of extended use. Thankfully, their capacity can also fully regenerate during periods of non-use, whilst your system is not being used. So if you are intending to run your system for several hours or more at a time, a fifth stage is highly recommended.

6 Stage RO/DI System

The 6 Stage RO/DI System features a second deionisation resin stage. With a single DI resin stage, as the resin becomes close to exhausted, it will start to allow some impurities to pass through due to a phenomenon known as purging. This occurs as the resin purges ions with a weak electrical charge, in preference of ions with a stronger electrical charge. One of the first ions to be purged is silicon/silica due to having a very weak, negative charge. By adding an additional stage you can safely use the first DI resin stage until it is fully exhausted as the second DI resin stage will catch the released impurities. This will allow you to also save on DI resin, eliminating waste and ensuring the purest water possible. Once the resin has been fully exhausted, you simply replace the resin in the first stage and swap the 2 resin cartridges around, ensuring you always have a fresh, full DI resin cartridge in the last stage.

Pressure Gauge 2 Pressure Gauge

In order to operate correctly, the RO/DI system will require a water supply pressure between 50-100 psi which is most easily checked and monitored with a pressure gauge. Below this pressure, your system will produce higher levels of wastewater and the RO membrane won't be able to maintain and/or achieve the specified 99% rejection capacity. This can lead to increased DI resin consumption which can be very costly. On the other hand, you can also damage an RO membrane with pressures above 100 psi. Although pressures this high are typically only found in industrial and commercial areas.

A pressure gauge is also an ideal way to determine when pre-filters need to be changed. As your sediment filter becomes clogged it will cause your pressure reading to drop, indicating its time for new sediment and carbon filters.

Available options:

TDS Meter 3 TDS Meter

A TDS meter allows you to monitor the Total Dissolved Solids (TDS) or impurities in your water. By monitoring the water your RO/DI system is producing you can rest assured it is operating correctly. A rise in TDS of the water coming directly out of the RO Membrane can indicate the membrane has reached the end of its life. If this goes unnoticed and the membrane is not replaced, DI resin consumption will rapidly increase, which can be a costly oversight.

While all of our DI resin is colour changing to indicate when it has become exhausted, testing with a TDS meter ensures pure 0 ppm TDS water is being produced for use in your reef aquarium.

Our TDS meters are available in either 2 or 3 sensor models so can measure water quality at multiple points with a simple flick of a switch. We highly recommend measuring your TDS level directly after the RO membrane, after the DI Resin and/or the source water entering the system.

Premium Water Saver Upgrade 4 Premium Water Saver Upgrade

The reverse osmosis process can be wasteful, typically generating only 1 litre of usable/filtered production water to every 2-4 litres or wastewater. This wastewater is normally discarded or plumbed directly into a drain. While it can be used for things like watering your garden it is often far more desirable to reduce this wastewater and the most effective way to do this is with a second RO membrane. This means before being discarded the wastewater of the first RO membrane is then passed through a second membrane. This results in half the amount of wastewater being produced and double the amount of usable production water.

Membrane Upgrades 5 Membrane Upgrades

By default, all of our systems feature 50 Gallon Per Day membranes which produce approximately 7.8L of water per hour. You can opt to change the membrane(s) for a larger size to increase the production rate based on your individual requirements.
