Excellent purchase saves time on cleaning my tanks and the fish are happy.
These are great. My aquarium water has never looked clearer. From now on I will only use Hydro Filter Replacement Sponges. I will be buying again!
I have bought several of these and they are the best! I have tried cheaper brands and they do not work as well and require more cleaning.
I love these filters,I heard alot about them . The water is crystal clear...
