Description

* Formerly named “Tap Water Purifier” An easy-to-use, single-cartridge tap water filtration system that removes impurities from tap water, making perfect, deionized aquarium water. Filter resin changes color when it`s time to replace cartridge. Used cartridge can be replaced without tools in minutes. Comes fully assembled and attaches to any faucet in seconds. Includes 4 oz. bottles of Electro-Right and pH Adjuster to treat the filtered water, faucet adapter and tubing. For freshwater, saltwater, African cichlid or community aquariums. How many gallons of water will the Tap Water Filter make? The amount of deionized (DI) water produced by the Tap Water Filter depends entirely on the level of minerals, heavy metals, phosphate, nitrate, etc. that is in your tap water. Each cartridge has a fixed ion exchange capacity. In New York City, for example, aquarists can produce up to 300 gallons of DI water with a single cartridge. An aquarist in northern New Jersey, however, made 15 gallons of water. An analysis of the NJ water showed very high levels of copper, zinc, phosphate, nitrite, and nitrate in addition to the normal hardness minerals. A heavily polluted water source will use up a cartridge much sooner than a water supply low in minerals and pollutants. Most aquarists produce somewhere between 50 and 150 gallons per cartridge. My original cartridge made 75 gallons of deionized water, the second cartridge made only 50 gallons. Why? The level of dissolved minerals and pollutants in tap water can vary daily. The level of these dissolved substances is measured as Total Dissolved Solids (TDS). The tap water in our laboratory varies from 200 to 400 ppm TDS on a daily basis. Our Quality Control Department pulls Tap Water Filters off the production lines and tests them with our tap water. They have to know the TDS of the tap water the day they test the cartridges. Why? A jump in TDS from 200 to 400 ppm means that a cartridge will produce only hal
