How frequently to change the filter depends on what type of filter you have. There are mesh filters that filter large particles of uneaten food, feces, etc. - these often just need to be rinsed to remove the material and that is it. If they get damaged in any way, that is when they need to be replaced. Other filters that remove toxins - often carbon filters or ammonia filters, have a set time frame that they should be changed with. This time frame is often set by the manufacturer, and usually ranges between 1-3 months, but you can look at the package or talk to the pet store where you purchased it for more guidance. The biological filter, which is made up of a surface for bacteria to live on, usually don’t need a great deal of cleaning as you can kill all of the good bacteria. I hope that helps to answer your question - if you need further assistance, I would recommend a store with fish experience, or we can do a consultation together here as well! Good luck!
