Aquarium – Reverse Osmosis System. This System is ideal for the fish enthusiast. Our system is filled with 350gms of nuclear grade Purolite Resin, the best in the world, & has a 50gpd reverse osmosis membrane.
DI Resin removes the mineral content of the water back to zero, which is great for fish. After water passes through both the reverse osmosis & DI Resin the pH can be 6 or lower depending on temperature etc. The water is now classed as acidic & not recommended for prolonged use as drinking water
