10/10 will buy again. For future reference I would probably only put this size in a 75g or larger, and get a smaller size for the smaller tanks.
Great quality and doesn't break the bank. Easy cleaning and keeps my tank and inhabitants happy.
I got this a week ago and cannot believe the difference in my water. The water is crystal clear and my fish shine like never before.
Highly recommended A++++
Wasn't sure if it would do the job but after listening to Cory's explanation about them - decided to give it a try. Works great and is definitely clearing up the water and the fish and plants all seem happy. Fast service (as always). Aquarium Coop is the best!
