EasyPro Eco-Series Sonata Waterfall Filter, 18" opening

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.

Prelude Filter includes:

• Filter box with “Spliner Lock” system
• Two filter pads
• Two bags of Bio-Blox media (two cubic feet)
• One 1-1/2″ PVC male adapter.
