Next-generation regenerable phosphate adsorption resineffective in marine aquaria; will also remove silicatesFar more effective than activated alumina and granular ferricproductsWill not negatively impact water quality nor release phosphateor silicate once exhausted; will not break up or disintegrate like ferric medias, and contains no aluminum to dissolve in aquaria and harm inhabitantsSynthetic polymer resin beads provide for durability and excellent flow characteristics; may be employed in fluidized-bed, canister, or passive filtrationRegenerable up to five times, dramatically increasing costeffectivenessBasic Instructions: Prior to first use, rinse resin under a stream of purified water. For initial application on aquarium, use 1 ml of PhosphatR per 1 US-gallon of water in system and monitor phosphate concentration during usage. Subsequent application of resin may be at the rate of 2 ml per 1 US-gallon.
