Those things are really very large. I've broken through a tablet and a packed Hälfter in the swimmer who always rumtreibt in the pool. The other half of the pump to the filter. So the middle of the Wasserströung in pump he was well distributed in the pool. The pool had a green coating on the floor. This is thanks to the tabs away again. However, it takes a few days. But then the water is clear again. So a great result I did not expect. If 6 stars were possible, I would give them. Fast Delivery. Highly recommended.
