Just an FYI, each package only contains 1 sponge (filter floss comes in a 6 pack). . . This perfectly fits the trays inside the cascade 1200 and 1500 canister filters. The sponge is quite coarse and will catch the biggest debris particles. However you'll want a tray or two loaded with filter floss to polish the water. As for maintenance of the bio-sponge, there's really no reason to replace this product any sooner than once a year. To clean it: pour the old canister water into a bucket, then take and wring out this "biosponge" in there. Wash it off using the old aquarium water and once it's fairly clean, put the sponge right back into the filter. Don't use city tap water to wash this because the chlorine will kill the beneficial denitrifying bacteria. I say 5 stars out of 5 because it perfectly fits the filter tray, the price isn't outrageous, and it will last a really long time.
