Aquarium RO & Deionization

Aquarium RO Water Purification Supplies

Filtering tap water is something many aquarists have chosen to do, as it removes all harmful chemicals and minerals from the water rendering it neutral. RO water purifiers (Reverse Osmosis) is one method used, while other devices such as the API Tap Water Purifier use DI to purify the water (Deionization). Both methods produce a much higher quality water than standard tap water. If using this water for freshwater it is usually best to use an RO water conditioner to restore some properties to the water before use, while if using it for saltwater that is not necessary.
