FilterMedia

Hi

Do you replace the filter media say after 2 years? or can we use it forever? This relates to eheim filters using subtrate pro or mech pro

Thanks!

As long as the bio-media is still solid (ie. not breaking apart or crumbling into dust), then it can continue to be used without issue. Not necessary to replace it.

I had used my filter media for more than 4 years. Those that had become smaller over time will be replace. The rest still can used.
