BulkReefSupply.com also carries aquarium carbon, GFO and Biopellets – all a must for keeping your reef aquarium water clean and crystal-clear. By filtering your tanks water with activated carbon and GFO phosphate remover, you can extract the toxins, phosphates and color pigments produced by the aquarium's inhabitants. If not kept at bay, these accumulated toxins pose a threat to the health of the fish and corals as well as give the aquarium water an unappealing yellow tint and feed algae growth. Our BRS Biopellets are produced specifically for de-nitrification of bacteria in saltwater aquaria.
