External Pond Filters

External pond filters sit outside of the pond and require a pond pump to push water through them and then back into the pond. External filters include pressurized filters and gravity or waterfall filters. When choosing a pump for an external filter, make sure you do not exceed the maximum flow rate of the filter (gallons per hour) or you will risk running too much water which could overflow the filter. We offer a wide range and types of external filters that will ensure your pond remains healthy and clean.

TetraPond Bio-Active Pressure Filters

Great pond filter
Pros: Great filtration, easy to back flush.
I have had this pond filter for around five years. It has worked well and is easy to operate. If this one ever breaks, I will buy another.
