Use and Care Manual

To ensure your water is balanced we have created the
following chart with suggested HTH Spa
™
Care Products,
which deliver optimal product performance, comfort and
crystal clear water.
Follow label directions for each product and allow each product to dissolve
and dispense before adding additional products to the pool. Use an HTH
®
test kit that measures all these ranges. Re-entry into a treated spa is
prohibited with chlorine levels above 5 ppm due to risk of bodily injury.
