Necessary filter item
Necessary aquarium filter item I buy these on a regular basis. They do an excellent job of filtering the aquarium. Only last so long as they have to be rinsed every few days.

Do what they are supposed to
These are pretty good, a bit expensive for what they are. They do clog up pretty quick so won’t last that long before they need to be replaced. When you try to clean them, they are a bit delicate and can rip
