Do I need to run the jets when using the Leak Sealer?

If your spa allows the jets to run, they may be used to help circulate the product. If not, operating the circulation pump alone is sufficient.

Turn the circulation pump off before adding the product. Thirty minutes after application, turn the circulation pump back on and run it for 8 hours.
