I had to make sure they worked the same as the Fluval brand which was unavailable for weeks before I left a review. I use them in underwater goldfish pond filters. At this time of year, with the advent of heat, they need to be changed more often. Remove them from the hose every other day, but they still need to be replaced more often in the summer. Very happy with them!
