Aquarium RO/DI system

Removes up to 99% of all impurities - including silicates - for clean, clear aquarium



Aquarium RO systems
Clean, pure water is a priority for all fish. No equipment is more effective in helping create ideal water conditions as Reverse Osmosis (RO) units. These units filter out up to 99% of chemicals found in tap water by forcing tap water through a semi-permeable membrane that removes 90-99% of tap water impurities. The result is water that is free of minerals and other contaminants.
Our Aquarium RO Systems meet stringent standards and far exceeds the quality of systems from other manufacturers. A wide variety of options ranging from economy 3-stage units to top of the line 5-stage RO/DI units are available to suit your exact needs.  

Deionization (DI) filters
De-mineralize filter takes the full size RO to a higher level of filtration. It is an excellent selection for reef enthusiasts and other serious aquarists, especially those who live in areas with exceptionally high levels of phosphates in their tap water. Our unit includes: sediment pre-filters, carbon pre-filters and TFC (Thin Film Composite) membrane, Deionization (DI) post-filters in clear housings. The post deionizer takes the small percentage of contaminants that the membrane could not remove and filters this to greater than 99.99% pure. It will give you 0 ppm TDS, Conductivity attainable less than 0.1uS/cm or resistivity of close to 18 meg.ohm (click here for more information)

Build-in Pressure Gauge
The minimum operating pressure for a RO (reverse osmosis) unit is 50 psi (pounds per square inch). This unit build-in pressure gauge to monitor the operating pressure of the system. If the operating pressure is too low, an RO pressure boosting pump can be added to increase the operating pressure to the ideal range.

Why do I need RO water ?
Tap water often contains impurities that can cause problems when added to an aquarium. These include phosphate, nitrate, chlorine, and various heavy metals. High levels of phosphate and nitrate fuel aggressive algae growth, and copper, often present in tap water due to leaching from pipes, is highly toxic to invertebrates. Because RO filters remove practically all of these impurities, they are becoming more popular among aquarists, particularly marine hobbyists. (please click here for more information)

(Stage 1) 5 Micron Sediment Filter :
With only five micron rating. It is effective in removing dirt, rust and sand particles.
(Stage 2) Carbon Block Filter:
It takes out 99% of the chlorine and organic chemicals. It provides enhanced reduction of taste, odor, and color. Protect and prolong the life of membrane.
(Stage 3) Reverse Osmosis Membrane:
A thin film composite (TFC) high quality membrane that processes 50 gallons per day. It remove the following hard water contaminants that may be present in your water: lead, cooper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium.
(Stage 4) Deionization (DI) Filter:
Produce 99.99% pure water by simply attaching this convenient deionization filter with RO unit. Convenient post RO filtration DI unit (RO/DI unit) provides crucial supplemental filtration to remove most impurities for pure polished product water. Excellent in areas with hard water. Produce 99.99% pure water. It will give you 0 ppm TDS, Conductivity attainable less than 0.1uS/cm or resistivity of close to 18 meg.ohm
