fish tank filter cartridges
How often should You change filter cartridges on your fish tank?

I have a 55 gallon fish tank powered by two 60 gallon filters. Each filter requires 2 filter cartridges to run. I was wondering if i could go a little longer without changing them because there are two of them. I usually change them once every 3 weeks, but that runs me a lot of money, especially when I got another 29 gallon tank also power by a 60 gallon filter that needs changing. I vacuum my tanks and do a 20% water change once a week. Any suggestions?

BTW the 55 gallon only has 6 afican cichlids in it.

what kind of filters are you using?

i like to use the aqua clear line of filters, they have bio, chemical, and physical filtration and the sponges (physical) can just be rung out and washed out instead of replaced
