Very nice build quality!!! Bigger than it seems on the photos. Made my koi pond clear in less than 24 hours!!! I put this device after the main filters but in front of the pump which returns the water into the pond. So all ozone bubbles get sucked into the pump and mix with water in the tube (it is about 10 meters long) while the water is going back to the pond.
