Gravity Flow Pond Filters

I needed a filter in a hurry and the staff did everything they could to help out.  Emails were always answered promptly and I received my order quickly.  I received a defective thermometer and even that was quickly replaced with no problems.  Within a week, the filter allowed me to see the bottom of my 2.5 ft deep pond — something that I hadn’t seen in months.  Would I do business with PondUSA again? Absolutely.  In fact I’ll be placing my next order within the next couple of weeks.

At we carry a variety of gravity flow filters from manufacturers like Matala and Oase.

Gravity flow or box filters are installed outside of the pond and incorporate mechanical and biological filtration designed to eliminate dirty pond water.
