Directions For Use: Rinse with fresh water (preferably reverse osmosis or deionized water). Warning: Product may get very hot the first time it is wet. Use rubber gloves and/or place in a plastic container while rinsing. Place in a large mesh bag (800 micron) or a canister filter, directly in the water flow. Make sure water flows through the material and not just around it. Leave for eight hours to two days maximum (as with any phosphate adsorber, phosphates can be re-released into the system if initial charge is left in the system continuously. If you want to leave in the system to keep phosphates low or to remove silicates, replace initial charge with brand new, and change on a regular basis.) For silicate removal, phosphate must be first removed, then a new charge of Phosphate Sponge must be left in the system for several days. Renewal: For phosphate removal, renewal may or may not be possible. At best, product may be renewed two times, depending on the circumstances of use, and capacity will be much lower each time. To renew, spread 1/4" thick on a baking pan. Place in a 450 degree (F) oven for one hour. Let cool. Rinse with fresh water and re-use. Do not use pan for food. Keep out of the reach of children. For aquatic use only.
