Wave Rill Waterfall is one of three attractive upgrades for your Affinity Pool. It can be retro fitted to any existing model and uses the Inpond to run. Fittiing a waterfall adds further features to the pond. The gentle tinkling of water is extremely relaxing and adds tranquility to the garden. On top of the pleasure you will get, the movement of the water helps to oxygentate the pool, giving your fish a healthier place to live.
