When you say "switched out", do you mean you cleaned them, or literally swapped the old sponges for new ones?

I have several HOB's mostly AC's, and a canister, and I probably keep the same sponges for a year. Filter floss tends to break apart sooner, so I replace that stuff maybe every 6 months. Once a month, a few squeezes, sit for a few minutes, and a couple swooshes, all in tank water, and I'm good to go (except for the one prefilter I use on an AC70 - that gets squeezed in running tapwater as many times as it takes to get clear water ...and those only last a few months due to this abuse).
