Betta Duo - Filter Maintenance Schedule

1C Cartridge - Change every 4 to 6 weeks
102C Ceramic Cartridge - Change every 20 weeks
113S Sponge Pad - Rinse in aquarium water, replace every 12 months
102i impeller - Change every 12 months

Please note: In order to maintain the optimum biological balance in your Betta Duo aquarium it's best not to change every item at once... swap one item at a time, a few days apart to allow for bacterial re-colonisation.


Maintaining the Betta Duo Trickle Filtration System

Weekly

Check that the water temperature is correct and that the filter pump is running well and that water is flowing through the filter media. Ensure the intake / strainer isn't blocked. Check that the 113S Sponge Foam Pad isn't clogged and rinse in a little aquarium water if necessary.

Monthly

Every month to six weeks replace the 1C Carbon Cartridge as the carbon becomes exhausted within this time frame. The Carbon and Wool cartridge cannot be rinsed and must be replaced. Check the filter pump and in particular that the impeller is moving freely and isn't blocked with aquarium debris. Check pipework. ** Every fourth month replace the 102C Ceramic Cartridge **

Yearly

It's good practice to replace the 102i filter pump impeller once a year. It's worked extremely hard, spinning hundreds of thousands of times and changing this small but essential part will help prolong the life of your Aqua One filter pump.
