Hello, i'm a newbie to looking after fish, me and my partner bought a tank at the ideal home exhibition about 6 weeks ago. I've got a few questions, i'll post the others elsewhere on this forum. My first question is, how often should you change the filter cartridge? We have a Resun SF-300 filter, any help is much appreciated. I only cleaned the filter for the first time a few weeks ago and it was filthy! I try and do it once a week now.
