Hey everyone,

I’ve recently joined this forum because I finally got myself an inflatable hot tub. It’s honestly one of the best things I’ve ever bought—super relaxing after a long day. But now that I’m using it regularly, I realize I have no clue what the best way is to maintain the water properly. I know you need chemicals to keep the water clean and safe, but I’m a little confused about which ones are best for inflatable tubs specifically.

Some people have told me you can use the same sanitizers as you would for a regular spa, like chlorine or bromine tablets, but others say you need to be more careful with inflatable models because of the vinyl liner. I’ve even seen warnings about tossing tablets directly in since they might damage the walls over time. That got me thinking—how are you guys managing your inflatable hot tub chemicals? Do you stick to the basics, or do you buy special formulations designed just for inflatables?

For example, I came across a couple of sites that sell inflatable hot tub chemicals packaged in starter kits. They usually include chlorine or bromine, pH balancers, shock treatment, and test strips. Has anyone here tried those? Are they actually worth it, or is it better to buy everything separately?

Personally, I’ve only tried chlorine granules so far. They seem to work fine, but sometimes the water still looks cloudy, especially after a few friends come over and we all get in. I’ve read that bromine might be better since it holds up in higher water temperatures, but I’m not sure if that’s true for inflatables as well. What’s your experience?

Another thing I’m curious about is balancing pH and alkalinity. Honestly, it feels like chemistry class all over again! I get that pH needs to be in a certain range so the sanitizer works properly, but I’m not always sure how to correct it without overdoing it. Do you guys have a routine for testing and adjusting, or do you just add stuff when the water looks off?

One of my biggest concerns is safety. Since inflatable tubs don’t have the same kind of filtration systems as permanent spas, do you find yourselves needing to add more chemicals more often? I usually test twice a week, but I’m wondering if that’s too much or not enough.
Also—this may sound silly—but how do you store your chemicals? I’ve been keeping mine in the garage, but I read somewhere that moisture and heat can make them less effective. Is it worth investing in a proper storage container, or am I just overthinking it?

So yeah, I’d love to hear your thoughts:

1. What sanitizers (chlorine vs bromine) do you prefer for inflatable hot tubs?
2. Do starter kits make sense, or should I buy chemicals individually?
3. How often do you test and adjust your water levels?
4. Any storage tips to keep chemicals effective?

I think a lot of new inflatable hot tub owners (like me) are in the same boat—excited to use it, but overwhelmed by the water care side of things. If we can share routines, brands we trust, and maybe some do’s and don’ts, it’ll make hot tubbing way less stressful and a lot more enjoyable.

Looking forward to hearing from all of you!
