The pump is with the UV timer you can choose 3 different times: 4 hours, 8 hours and 24 hours, depending on the water quality.
Adjustable flow rate/direction of the water outlet: the maximum flow rate of the built-in filter is 400L/H, and the size of the water outlet can be adjusted as needed, and the direction of the water outlet can be adjusted 180° left and right. The water outlet is equipped with a rain shower and an oxygen nozzle, which is decorative and practical.
