Aquarium Advice Apprentice
I have 3 tanks. I use sub filters on all 3. They work really great for me. I customized my insides. I cut the the stock sponge inside half, and the cut a small chunk of both halwes. In the middel i put filter wool on both sides with amonia remover pebbles between the wool. Two of my filters have cartidges wich i fill with activated carbon pellets. I clean my filters once a week in water from my tank i get from water changes. When cleaning the filters i replace the amonia rocks and carbon each time. Is it necesary? I mean each week? Or can i do every second week? And is my filter media setup ok? The one without the carbon cartridge i just put carbon mixed with the amonia remover. Any thoughts or advice?
