Yesterday i went out and found my waterfall NOT working. The pump had come loose from the hose that returns water to the falls. It was churning muck inside the box it sits in. I had to clean out the box the pump sits in and clean the waterfall filter. Everything is working fine today and the water is nice and clear.
Richard built my waterfall, it is also a filter and does a great job. I have pictures of each step he took to build it and I think i may give each step here and then add a page for it latter.
