EasyPro Pond Products WF18E Sonata ECO-Series Waterfall Filter, for Natural Biological Filtration, is a Patented, Tool-Free System Ideal for Koi Ponds and Water Gardens Up to 1,800 Gallons

Works great for my waterfall in my small pondEasy to clean as well

Item was delivered very quickly. Just in time to install the filter over the weekend. Two things that I do not like. One: The filter cover is not included. This seller does not offer the cover for the filter which I was able to buy through a different retailer (not on amazon). Two: I wish it had some built in piping that I could hook up my intake piping on top, but still have it enter the filter on the bottom. I partially buried the filter and had to install some extra piping because I did not want the connections buried.Filter is working great. The pond has never looked cleaner/clearer. Cleaning is a snap. Just lift the filter bags and hose off.

It ended up being bigger than I had in my mind but it's a nice size for my application. It's very sturdy and will last a long time.

This will be an easy way to help support a healthy pond.

Seems very well built and heavy duty to last a long time. Media bag is extra large and comes filled with foam bio media. Super fast shipping and delivery.

well built. Why must the customer do a second order and pay AGAIN to have it shipped to get the LID for this waterfall filter? Shame the manufacturer has seen it as another way to get more money from the customer. Would have been 5 stars to have marketed the filter box AND lid together as a complete unit.

We have this installed at our waterfalls. We had a different type of filter which was not doingg the job. I am pleased with this unit. The Water in my small Koi pond is nice and clear. Thw Koi pond holds around 800 gallons. This EasyPro waterfall filter was a great purchase.

Haven't installed it yet, but I've used products exactly like this before. It will work fine if I don't screw up the liner on the waterfall. I've no experience with the foam type media for filtering. I've used lava rock and Bio Balls in the past.
