Clorox® Pool&Spa™ Spa Bromine Tablets- Bromine Tablets for Spa & Hot Tub, Low-Odor Sanitization, Kills Bacteria, Restores Water Clarity, Slow-Dissolving, 1.5LB (Pack of 1)

Yep, it is some kind of Bromine salt which is what I wanted. MUCH nicer fore kin and mucous membranes and stinks less than Chlorine. Ozone generators would be best. Behaviour in the hot tub is as expected, no better or worse than others. Obviously prevents any algae growth. pH, dissolution and water hardness need very regular measurements to be certain about. This is ctually very important. Again, never mix the dissolve Bromide with ANY other chemical especially bleach, or you could cause you or your loved ones some serious damage.

I use these in my kaboom continuously clean toilet cleaning system instead of buying their refills. This lasts me a long time and I rarely clean inside my toilets. I know how gross that sounds, but it's true and my toilets look new. Between these tablets and the way my Cadet 3 toilet swishes the water around the bowl, there is really no need to do anything other than flushing. I don't get mineral lines because I have a water softener, but these tablets for me kill and prevent bacteria in the bowl with every flush. These do not have an overwhelming odor to them (like chlorine tablets) and after a few hours, you can't smell them at all. 2 Tablets last about 2-3 months in each of my bathrooms and the price is awesome here on Amazon, $15ish. For those of you who are using this in the toilet tank.... my tubing that Kaboom came with, eventually swelled and turned white. I have searched for a few years for just a replacement tube in the local stores, but they are not sold. They tell you to buy a whole new fill tube kit...NO, I will not do that for 6" of tubing. I accidentally found, here on Amazon, silicone tubing and 10Ft of it if you should need to replace the tubing. It is item # B08H597B7T you can copy and paste into the search bar. You may be able to find another silicone tubing locally that works, or even here on Amazon. The measurements are: 0.12'' (3MM) ID, 0.27'' (7MM) OD. Being I had 10 feet of it, I replaced all tubing in all toilets now and still have some left over. It works EXCELLENT in the toilet tanks and the bromine has not distorted the silicone tubing at all. The silicone has some stretch to it so it will fit onto the fill valve and also the Kaboom cartridge and be snug without leaking at all.

Worked as advertised

Useful for pool

Keeps our saluspa clean!

Works best in my hot tub

Good stuff, I have been using it for years for my hot tub.

We have tried many different tablets. This one works the best for us. Many don't keep the water as clean and fresh as long as this one does. Also, it doesn't have a strong smell of Chlorine like others do. Container is easy to open but also childproof.

Used in our hot tub and worked as expected.
