Review: Great quality and easy to DIY - Absolutely perfect for a yard pond. It for the 1/2 tubing that we got perfectly. There’s no need to buy an expensive kit. We got everything for under $100. Super easy to install with tubing and some glue. Made well and water flows fine. So far, 3 months in we haven’t had any leaks! Super functional and makes a beautiful addition to our yard on a diy budget! We just added a few landscape rocks on top and it’s held up well! Review: Works as intended. - This spillway works very well. It was easy to set up. The hardest part was trying to decide where to put it. (I have a much larger pump and waterfall that are electric, but I am trying to go all solar.) It has helped filter and move the surface water to keep the water oxygenated. I did have to buy a short hose to attach it to the end of my pump tubing. The hose fits perfectly and does not leak which is important, since it sits outside the liner. I have a solar pump attached to it, and it runs very well during the day. I did also buy the filter media and I rinse it out when it gets dirty. I currently have a brood of toad tadpoles that are very happy with this spillway. ## Features - EASY WATERFALL — easily create a waterfall or a disappearing water feature and enjoy the soothing sounds of moving water.
