So, I have owned an inflatable hot tub for over 3 years now, here is a rundown of what chemicals I use for my hot tub. In the video below, some of the products are no longer for sale, but I have put the equivalent products here below.

These bromine tablets are great. Get them in bulk. You go through them more than any other chemicals on this page. They are the most important chemicals to get.
Bromine Test Strips for an Inflatable Hot Tub
You don’t have to get these test strips specifically, but they are the second most important items on this list. You need to test your chemical levels. Get these or something like these bromine test strips. Just make sure they are for the chemical bromine.
The rest of the items on this page you can get and then keep for over a year. They don’t run out that quickly.

Shock Oxidizer for an Inflatable Hot Tub

I only use this when I first set up the hot tub and every time I refill the inflatable hot tub. So, this lasts a while unless you refill the inflatable hot tub every month.
Inflatable Hot Tub Defoamer & Spa Defoamer
This will get rid of foam in your inflatable hot tub. Use this when needed.

Inflatable Hot Tub Clarifier

What happens if your hot tub gets too cloudy? Use this clarifier when needed. Make it clear so it “looks” cleaner.
Use Baking Soda for an inflatable hot tub

Yeah, Baking Soda. Baking soda is crucial for keeping the PH levels in balance. If the PH is too low, you can use baking soda to raise the PH and alkalinity levels for a more enjoyable hot tub experience.
