Hey everyone! I'm new to the forum and just wanted to share my duck pond experience so far.
This is my Lowes 125 gal pond with a diy biofilter. I am using an above ground pool pump that I had in the shed to circulate the water. The plants I believe are taro that I pulled from the creek behind my house. I have two ducks and have yet to dump the water, only top off every other day and it's still perfectly clear! It's been running now for about a month and the ducks love it, especially since it's in their 10ftX12ft pin.
That's a little out of my price range, but I love the bio-filter!!!!
