How often are you supposed to change the filter?
How often are you supposed to change the filter?
The filter pad? Or media like bio rings? Anyway.... Just swish it around in tank water. No need to replace until its literally falling apart.
When the sponge itself becomes deteriorated. Should be over 2 years. At least for me. Just rinse it in tank water once a week.
