Hi, it really depends on your water change schedule.
I have a couple of 10 gallons and a 20 gallon. I clean clean my filters once every two weeks and do a 50% water change once per week.
Remember not to clean the filter under a tap but use some of the old tank water to remove the debris
Hope that helps

Hi,

Sorry, I couldn't tell you. I have never shown, and wouldn't really know what to look for.
You are better asking Russelltheshihtzu.

Regards,
