i have many ac, but the reason i don't like them that much is because the sponges catch larger debri, not the unseeums, so i use filter batting in all them, but i either put it under the sponge at the bottom, or above the sponge and then bio rings on top,
when using the floss, it traps more stuff, so needs changed faster than without,
but i want it to clean the water, not be easier on me, ...
so put the floss lower down and the bio on top always, and change often,.. the amount of water flow thru the ac makes them great but the clog faster with wool,. because of the flow rate,.. mine have never leaked but when needed to change the basket will try to float up,.
