MetaSorb UHC. Excess heavy metals in water are toxic to aquatic life. These metals can come from the water source, food, artificial seawater mixes, therapeutic treatments, corrosion of metal equipment, magnets, pumps, etc. Mysterious ailments can occur in fish, corals, and other invertebrates when heavy metals reach a toxic threshold. MetaSorb UHC is made with patented, high-capacity polymers developed for the U.S. Environmental Protection Agency's Superfund program. Water-insoluble and non-toxic, the polymers rapidly bind and permanently remove metals from fresh and salt water, enabling the restoration of water quality. MetaSorb UHC is a fine powder packaged in a small, fabric-backed bag that is easy to locate in any area where high-volume water flow would facilitate contact with the polymer. Simply place the bag in any canister filter, back-hung power filter, or in the flow sections of any sump or filter chamber. After a few days, MetaSorb UHC can be removed, dried, and stored for later use or discarded. MetaSorb UHC can be reused multiple times. The case, sized for 1-250 gallon aquariums, removes up to 80 ppm of metals from 250 gallons. The case, sized for 500-800 gallon aquariums, removes up to 120 ppm of metals from 500 gallons. Use for pre-treating new water or freshly mixed artificial seawater, for removing copper-containing medications, and for removing metals leached from corrosive equipment.
