Sonata filter – for ponds up to 1800 gallons.

Eco-Series biological waterfall filters help keep ponds clean and clear while supplying an ideal base for waterfalls and streams. Pond water flows up through filter pads and filter media with high surface area allowing suspended debris to be trapped and beneficial bacteria to provide natural biological filtration.
Patented “Spliner Lock” system attaches liner securely and easily – no bolts, no silicone – no puncturing the liner.

These patented waterfall filter boxes are the easiest to install of any similar style filter on the market today
