In this episode of The Aquarist’s Edge, Art breaks down what actually happens inside sponge filters, canister filters, and hang-on-back filters, and why upgrading a filter can sometimes make a tank worse if the habitat shifts. You’ll learn how filter flow rate, surface agitation, and filter media choices shape your biological filtration, water clarity, and long-term consistency. 💬 Join the conversation: Have you ever upgraded a filter and your tank got worse?
