I Have just set up a 40 gallon tank with an Eheim 2073 (350l) filter.
The tank contains four small fantail goldfish (not more than an inch long).
The instructions don't say how often to clean and change the filter media.
Can anyone help me out with some advice?
I am completely new to using canister filters and so would welcome any advice.
Thank you
