How to use

Position the canister filter on a stable surface beside or under the aquarium, ensuring level placement and easy access to the lid and media trays. Connect the inlet and outlet hoses to the corresponding tank fittings, prime the unit following the manufacturer procedure to remove air from the hoses, and switch on the motor. Fill the media trays with appropriate mechanical, chemical and biological media according to water quality needs, and set the flow rate to achieve the desired turnover without stressing livestock. Regular checks of hose connections and seals are recommended to ensure leak-free operation.

Usage recommendations

Perform routine maintenance on a schedule: clean or replace mechanical media when visibly clogged, refresh chemical media as it becomes exhausted, and avoid replacing biological media simultaneously to preserve beneficial bacteria. Monitor flow rate and water clarity, and inspect seals and hoses periodically. Use media types suited to freshwater aquariums and adhere to manufacturer guidance for optimal performance.
