Sorry you have not been happy with the Chlorine Shock. If your pool is green then you will need to put at least three times the normal shock dose in at once. In some cases it may take 10 times the normal shock dose if the pool is very green. Please be assured that this is standard 65-70% Calcium Hypochlorite Granules, widely used on the market and we have had no other complaints about this product not working effectively, as you can see from the other reviews.
