A SOLAR Filter Kit!!! I have been on the hunt for a solar fountain that is powerful enough for a pond and not just a bird bath, and @poposoapsolar delivered!!! When building a pond you have to think about location and if you can run electricity to it, but with their solar products, you don’t have to worry about this!! The fountain does only work with direct sunlight on the panel, but when it is on, it is POWERFUL! I had to turn down the water outtake because of how much the water was coming out.
