Adequate Aqueon Filter

I may have ordered the wrong size for the our tank, but these do fit the small filter well enough to use them.

Gets dirty fast

These filters aren’t very good. They have to be changed out every 2-3 days.

I have been using these filters for well over six months now. I have no issues with them. They sit easily right inside the filter housing. Do pay attention to if your placing filter in front or back. Looks the same but it’s written on the tiny tab.
