What owners are saying
Questions, answered
Does it replace my chlorine or bromine?
No. It cleans, clarifies and conditions, but it doesn't sanitize. Keep your sanitizer at proper levels at all times.
Do I still need to shock?
Yes. 3-in-1 isn't an oxidizer, so use it in addition to your regular shock.
Will it work in my saltwater or inflatable tub?
Yes. It works in any hot tub type, and with chlorine, bromine, mineral, saltwater and biguanide systems.
Will it bleach my spa?
No. It contains no bleach or harsh chemicals.
How long until I can soak?
Wait at least 2 hours after adding it.
Spend less time on water.
More time in it.
