There is no exact schedule for filter cleaning as every filter is different however, one basic way to get an idea as to when it’s time to clean is by monitoring flow. Once you are able to see that the flow of water has slowed down, it is probably a great time to go ahead and clean your filter. The average rule of thumb is that filters should be cleaned at least once a month.
Choosing the best filter for your tank can also be difficult as there are different types of filters that can be used. Hang-on filters are a popular option that simply hang on to the class of the tank itself and is secured in that manner. Another popular filter option is what is known as a canister filter. A canister filter is a cylindrical apparatus that uses a pressurized canister to pump water in and then push clean water back into the tank. All in one filters are probably the most advanced as far as water filtrations as they also come with a built-in protein skimmer, media cartridge, probe holder, and much more. Filters in general come in many different sizes to accommodate your tank size.
