Yes but it is a designed for bigger pools so will not need floating full time: Here are our recommendations on how to use in a play pool or outside hot tub:
1 Float the Floatron on a sunny day for an afternoon.
2 Run the pump now and then or mix water well. If there is low volume circulation this may be left running during mineralisation.
3 As soon as the level of 3-5ppm copper is shown on the testkit provided remove the Floatron.
4 Once the level is established test every two weeks and re-mineralise as required.
5 After using the pool in the evening pour a small amount of chlorine into the water and run the pump for a minute. By the time the tub is used again the chlorine (bleach) will be gone.
