Water Purification | Mail Order Pet Supplies, Inc

The foundation of a thriving, healthy aquarium—especially for sensitive marine and planted tank inhabitants—is ultra-pure water. Tap water contains numerous contaminants like chlorine, heavy metals, phosphates, and nitrates that can fuel unsightly algae growth, stress your fish, and prevent corals from flourishing. Our comprehensive selection of Water Purification systems is designed to eliminate these harmful substances, giving you the control to start with a blank slate of pure H₂O for your aquatic environment. Investing in proper purification is the best way to ensure the long-term success and stability of your tank.

For the highest level of purity, explore our range of RO & RODI Systems (Reverse Osmosis and Reverse Osmosis/Deionization). These units utilize cutting-edge TFC Membranes to strip water of up to 99% of impurities, followed by a final deionization stage to achieve near-zero Total Dissolved Solids (TDS). This "liquid gold" is essential for proper mixing of saltwater and for topping off evaporated water. To keep your system operating at peak performance and producing consistent results, make sure to regularly replace your sediment, carbon, and DI resin cartridges with our high-quality Replacement Filters.

We also offer a full spectrum of Parts & Accessories to customize, maintain, and monitor your setup. From essential pressure gauges and TDS meters to specialized fittings and tubing, we have everything you need to build and support your water purification station. Protect your investment and your aquatic life by ensuring you always have access to the cleanest, most pure water possible.
