Chlorine tablets are the perfect size, for the reason why I bought them which was to use on my inflatable hot tub. the box it came in on the other hand is extremely hard to open, nearly broke my fingers opening the box! After opening the box 3 times it broke cause it's made of cheap plastic not it still does the job of keeping the tablets inside. Sorry I can't speak on the longevity of the chlorine tablets in the water, the tablet holder I have for the water is... Special. Might update this later when I get a new tablet holder for the water.

The chlorine level and effectiveness is perfect. One to two tablets in my hot tub floater keeps the chlorine level just right. But they only last about 3 days at most.

I don't know why chlorine tablets in general are so expensive, but I find that buying a larger bucket is more cost effective.

The lid is very difficult to get open. I don't have any kids or pets that could get into it, so I cut off the safety tab to make getting the bucket open much easier.

As anyone with a spa or pool you no how hard and expensive pool chemicals are. It was difficult to find these chlorine tablets in 1 inch size that fit my frog chlorination system. Most the time I’m crushing up bigger tablets to fit. Good price and speedy delivery love it.

5.0 out of 5 stars Only thing I use in my spa
Reviewed in the United States on July 20, 2024
My house came with a bromine hot tub that molded along & on the cover and head rests. I was always having to pull it out and scrub & the chemicals were always a mess (even without use). After replacing the water (& rinsing well), I switch to these tablets & never looked back. No mold! Even the mold on the cover I couldn't get off started to go away. (& no, the chlorine isn't showing high on the test strips) 1 tablet lasts 2-3 weeks for mine. I occasionally need to add baking soda, but the ph is always spot on. Never switching back.

This chlorine is the perfect small spa tablet size.

I bought a different brand 1" and they would last a week in my hot tub. These Clorox 1" don't even last 4 days.
