Use in freshwater aquariums, planted tanks, koi ponds, natural swimming pools, hydroponics, saltwater aquariums, and reef tanks to control phosphates and reduce algae. Safe for all freshwater and marine fish, invertebrates, plants, and pets.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eDetailed Instructions\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eHow to Remove Phosphates from Water and Reduce Algae\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e1. Place GFO media in mesh media bag in filter or sump, or directly in fluidized reactor in recirculating water flow.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e2. Initial starting dose = 1 gram\/gallon in media bag or fluidized reactor.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eStandard maintenance dose = 2 grams\/gallon in media bag or fluidized reactor\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eStart slowly since GFO removes phosphates quickly and effectively to avoid shocking your aquarium. Once phosphates are under control in 2 to 3 weeks, increase GFO dose to maintain consistently low phosphate levels.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eEXAMPLE STARTING DOSE: 8 grams = 1 level tablespoon, 16 Tbsp = 1 cup. 1 cup per 128 gallons to start in media bag or fluidized reactor\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eEXAMPLE MAINTENANCE DOSE: 1 cup per 64 gallons standard maintenance dose once phosphates are under control in media bag or fluidized reactor\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e3. Monitor phosphates, add or change media when levels start to rise, or if algae increases. Sometimes the algae consume so much phosphates, the levels test low while algae growth is still present. Continue increasing until algae is controlled, or switch to High Capacity GFO HC for stubborn algae problems.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e4. For optimal effectiveness, do not allow overall phosphate levels to test above 0.05ppm. Test water coming directly from the phosphate reactor for phosphates. If any phosphates are present, GFO should be increased or replaced.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e5. For best results, pre-filter water going into the reactor, and water going out.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eEXAMPLE: Filter sock on effluent to trap fines, especially with new media.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003ePro tip: Remove all sponges before and after media in reactors and replace with plastic mesh to prevent clogging. Add small check valve to pump side of water line\/keep return line submerged to prevent back siphoning into pump in case of a power outage.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e6. Rinse all new media and discard discolored water from rinsing before use.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003ePro tip: Use bucket full of tank water and submerge pump and reactor. Run pump with return line running to drain until discoloration stops, then return line back into bucket. Run for a few minutes, checking for proper fluidization. Check for air bubbles or pockets, and gently tap or tilt reactor to eliminate them. Return pump and reactor to sump or tank together.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e7. Check weekly for good flow and fluidization. If clogged, dump reactor contents into 5 gallon bucket with tank water, stir and pour off debris. Media can then be returned to reactor in part or whole.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003ePro tip: Use this technique when changing media, and save approx. 1\/4 of old media to mix into new media, keeping bacterial cultures stable to prevent bacteria or algae bloom from media change. If used in canister filter, use micron bag to hold GFO preferably in thin layers to keep good flow, and reduce channeling through media.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e8. If any negative coral reaction is noticed after new or changed media, reduce the amount by half. Dropping phosphates too quickly can cause shock. Once established, overdose is unlikely and phosphates will not leach back into the system.\u003c\/p\u003e","brand":"Kolar Labs","offers":[{"title":"250g","offer_id":67288985698608,"sku":null,"price":24.99,"currency_code":"USD","in_stock":false},{"title":"454g","offer_id":67288985731376,"sku":null,"price":39.68,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0876\/2949\/6624\/files\/Kolar_GFO.png?v=1783226197","url":"https:\/\/giomarine.com\/products\/kolar-gfo","provider":"Gio Marine","version":"1.0","type":"link"}
