It works for 2 weeks, 1 of them every day for 8 hours, cleaned 12 cubic meters of dirty water (the water was mixed with clay and dirt), after that I just cleaned the filter (sand) and everything became like new. 2nd week for 2 hours a day! The water became very clean as a tear! Well, of course the filter plus chemistry! Got pros: Powerful, quickly cleans dirty water, a large amount of quartz sand. Regarding noise, aunt, he drives 9500 liters of water at the exit, how would you like it to work as a fan on your cap? Take it and don't worry, it's a cool thing ! Different cons: The kit does not include 1 hose (38) for draining dirty water after cleaning and laying sand.
