So, I probably have this thread in the wrong spot, but I have a question about the filters on my tanks. I have been using filter cartridges for years now, but they cost a fortune and I'm having trouble actually finding the sizes I need.
Today I saw a video on youtube about using aquarium sponge in your filter instead of a cartridge. Would it be okay if I replaced the cartridge with some sponge?
I also saw that you can use polyfiber. Would this be better than a sponge? Shoud I use both?
If I do use sponge and/or polyfiber, how often would I have to clean it?
Thanks!
