- Drain Clamp (For Wastewater Line)
- Housing Wrench
- All Prefilters, RO Membrane & DI Resin
4 STAGES OF FILTRATION
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 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 3 – 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 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/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.
4 Stage 50GPD Essentials RO/DI System Recommended Conditions:
- Minimum Water Pressure – 50psi
- Max Water Pressure – 100psi
- Max Water Operating Temperature – 45°C
- Recommended Max TDS – <300ppm
If your home’s tap water pressure is below 50psi we strongly recommend the addition of a booster pump. All Reef Pure RO systems can have a pump added as an optional extra.
Pressure below the minimum required 50psi 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.
