Drain water and add water. Not very efficient and time consuming. Tried the frozen gallon jugs and it takes more than I can fit into a freezer to lower the temperature only a couple degrees. They make pool water coolers but they are expensive. When the water temperature is 90 degrees you cannot swim laps in the swim spa. It's useless as a swim spa in the hot summer months which here by the gulf is June through September.

I own the H2X 19 swim spa. It has the hot tub and swim spa with wall divider, meaning we can set the temperatures different for both hot tub and swim spa. We love it, but in the hot summer months the swim spa gets too hot (90 F) for swimming. Anyone of you found a cost effective way to cool the swim spa?
