Thunder PartsWater Pump Bio-Filter | Mechanical Pre-Filtration | Improves energy savings | Reduces premature clogging | Extends pump life | includes adapters for various pump types | Life by Air!

We were able to fit this filter setup onto our existing pump in our turtle pond as a prefilter to keep gunk out of our biofilter. As many may know, turtles are hard on filters, but this one holds up to the test! It keeps the snails out without clogging up. We used to clean the black sponge charcoal filter weekly, this one can go a month. Great purchase!
