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
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.
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 **
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.
