Aquarium RO System with Built in Pressure Gauge
Removes up to 99% of all impurities - including silicates - for a clean, clear aquarium

Aquarium RO system
Clean, pure water is a priority for all fish. No equipment is more effective in helping create ideal water conditions than Reverse Osmosis (RO) units. These units filter out up to 99% of chemicals found in tap water.
Our Aquarium RO Systems meet stringent standards. 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.

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 contains impurities that 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 essential for aquarists, particularly marine hobbyists. (please click here for more information)
