New Water Feature

My latest addition to the Koi Pond is a spitting frog. I thought it was a nice feature and it was easy to put into place. No electricity needed, tubing attached to the frog goes up to the top waterfall doe into the weir and the force of the water from the pump powers the frog! It adds additional oxygenation to the pond for the koi. I hope to be able to add more koi but have not been successful. The last fish I purchased were too small and did not survive the skimmer and the force of the water.
