SALTWATER AQUARIA OWNERSSaltwater Purification: The separated and normally recharged, as an Ion Exchanger, anionic resin column, may be converted into a very highly efficient adsorber by effectually neutralizing the charged resin for this adaption to purify marine and reef aquaria saltwater.
To neutralize the previously recharged, as an Ion Exchanger, anionic resin, for saltwater purification. Dilute the supplied cationic resin recharging fluid by 50% with DI water in a separate container. This is broken down as, 6 ounces of the cationic resin recharging fluid is to be mixed with 6 ounces of water purified through an operational DI column, in a separate acid safe container. The drained anionic resin column is to be filled with this dilute solution of cationic recharging fluid and stirred or drained and repeated once every 15 minutes for one full hour. The column is then to be thoroughly rinsed using at least 3 gallons of tap or DI water.
The use of the anionic resin, charged in the manner so indicated for the purification of saltwater, is usually performed as an inline unit and part of the aquarium circulatory system. This is accomplished by placing the column in-line with a bypass to allow normal water circulation with only a sampling of the aquarium water being passed through the anionic resin at a flowrate not to exceed 25 gallons per hour. Common practice is to flow only 5 gallons per hour through the unit.
