SpaChoice 3.5-Pounds Premium Brominating Tabs Sanitizer for Spas, Bromine Tablets for Spa Hot Tub, Made in USA

I have been using prefilled cartridges and these tablets in a floater is SO much cheaper and easier to monitor.

I waited for this product for a bit, so in the waiting period, I purchased a some other brand at walmart thinking bromine is all the same, but I was proven wrong, stuff sucked big time, the water quality in the hot tub went bad really quick, to the point where I started getting rashes on my legs. Finally received the SpaChoice, fluhed out the water, replace the bromine tablets, and bought some shocker just in case, but the tablets have been doing such a good job, I haven't had to use shocker yet the, ph plus bromine leves stay on point. I use 2 to 3 tablets on 275 gal, they last almost 2 weeks.

Doesn't dissolve quickly works great. Round tablet. I will order again.

Tablets work well.

If you run a bromine a hot tub, you probably use an adjustable floating dispenser to maintain bromine levels when not in use. These tablets are perfect for that. They are the small (about 1" diameter) tablets, not the large 3" ones that are occasionally placed directly in the skimmer. My tub is about 180 gallons, I keep one to two of these tablets in the floater at all times. They'll work best if you have already established a bromide bank with sodium bromide, as they activate the existing bromide into bromine. They'll work, somewhat, if used alone, but that's not the optimal way to maintain sanitizer levels.

Nice bulk buy. Fit Nicely in my hot tub floaty thing. Seems to dissolve slower than the other brand I used before. I like that. Keeps the hot tub free of microbes and keeps it clean. What else can you ask for.

I've checked plenty of options, and this seemed the best value, especially on a Subscribe and Save subscription. I like that I can use the bucket afterward instead of throwing away an unrecyclable plastic jug. Once you figure out how to easily get the lid off, you're good to go!

Works great. Only downfall, when I went to open it the latch broke pretty easily. Then I was unable to open it. Had to cut the lid off. Otherwise bromine worked wonderful.
