Fluval G-Series Aquarium Filters
Chemical Filtration
During the subsequent chemical filtration, all water flowing through the G filter passes through the chemical media cartridge. The Fluval G offers a combination of media options to make chemical filtration simpler and more efficient. Featuring high-capacity ionic exchange filtration media, the system will efficiently remove nitrates, phosphates and waste. For pure consumer flexibility, the chemical cartridges can be refilled with any type media the aquarium owner chooses. Regardless of chemical media type the design of the chemical cartridge and subsequent water flow ensures maximum water contact resulting in a highly efficient filtration process.
Fluval G3 / G6 Nitrate Cartridge
 The Fluval G3 Nitrate cartridge is for use with the Fluval G3 advanced filter and will remove up to 13000 mg of nitrate ion in fresh water aquariums. Nitrate concentration should not exceed 20 mg/L in freshwater aquariums; The Fluval G6 Nitrate cartridge is for use with the Fluval G6 advanced filter and will remove up to 24000 mg of nitrate ion in fresh water aquariums. Nitrate concentration should not exceed 20 mg/L in freshwater aquariums; Planted aquariums require approximately 5mg/L of nitrate as a source of nitrogen for healthy plant growth.
In a 300 / 600 L freshwater aquarium with a 30 mg/L nitrate concentration, the use of Fluval G Nitrate cartridge will quickly remove all excess of nitrate in a couple of days. If left in the filter it will then maintain a low nitrate level for a period of time that is strictly dependent on the type of aquarium (quantity and type of fish, type of fish food and so on). Nitrate is irreversibly trapped and bound and will not leach back into the water. The continuous use of the Fluval G Nitrate cartridge in aquariums with persistent nitrate problems is an effective solution against nitrate accumulation. If used as a quick solution to reduce elevated nitrate concentrations the cartridge can be removed once levels have normalized and then stored until required.
In the following example, a 600 liter freshwater aquarium was treated with the G6 Nitrate Cartridge. The concentration of nitrate was reduced from over 20 mg/L to less than 5 mg/L and remained around this value for over 30 days. Then the concentration started to slowly rise and was back to 20 mg/L in about six months. During this period no water change was performed. |
