The 3 Kg package've bought together with 3 liters Algenverhüter. Delivery came immediately by DHL. Although the most important thing in the pool cleaning is still setting the correct pH value in the beginning. But is this done: Algenverhüter and chlorine add and filter. So you get any clear pool. For almost 20 EUR you do not even get half of the amount supplied in the specialized trade. The quality is right also so clear case: Thumbs up!
