Works like magic!
I had problems with discolouration of my garden pm water feature and lack of water clarity . Treatment with solution made from the granules has solved all my problems. It was much cheaper than buying a specialist kit from the water feature supplier - need to be careful however to guard against splashes of the solution getting onto skin or into the eyes.
