Fluval U3 Underwater Filter Poly/Carbon

Work great, like advertise. I just wish there was a better indicator when to change the filters.

Great value for the buck!

Ive used several different filter systems on my various aquariums. I love this underwater one the most. No constant running water. It keeps the tank clean and the filter elements last a long time.

Maintains my crystal clear 55 gallon tank.

This review is for the foam pad component to the Fluval U3 reptile filter. We have had an aquatic turtle for aost 21 years. We have tried other filters and were quite happy with them. When they went out of business, we decided to try Fluval U3; we are beyond delighted with this system. The water is always clear, no algae, no smell, and it is quiet. Highly recommend Fluval U3; and its components of which this foam pad is one. Of

Good

Makes my fish tank nice and clean
