AquaDoc Bromine Tablets for Hot Tub & Spa - 1.5lbs Sanitizing Bromine Recommended for Hot Tubs

5.0 out of 5 stars Best Bromine Tablets I’ve Ever Used for Our Airbnb Hot Tub – Huge Bucket, Zero Complaints, Crystal Clear Water Every Time! I’ve been running a pretty popular Airbnb with an inflatable hot tub for the last two years, so believe me when I say I’ve tried just about every sanitizer under the sun. Chlorine tabs that smell like a public pool, off-brand bromine that takes forever to dissolve and leaves little undissolved chunks floating around, you name it. I finally landed on AquaDoc Bromine Tablets (the 3.5 lb bucket) and I’m never going back. This stuff is legitimately fantastic. First off, the value is insane. 3.5 pounds is a massive amount – we’re talking 6-8 months of heavy use for our 4-person hot tub that gets turned over 3-4 times a week with guests. I’m currently traveling in Europe for an extended period and was able to order this straight to my house in the States with no issues. Amazon shipped it fast, it arrived perfectly sealed, and my housekeeper (who speaks limited English and is definitely not a “hot tub expert”) had zero trouble figuring it out. She just pops 2-3 tablets in the floating dispenser once a week when she does her cleaning rounds and texts me a photo of the test strip showing perfect levels. That alone is worth five stars in my book. The tablets themselves are the perfect 1-inch size – they dissolve quickly and evenly. No more waiting 30 minutes for cloudy water to clear after a big group of guests leaves. Within 10-15 minutes of adding a fresh tablet (or shocking with a little extra if it’s been a wild weekend), the water goes from slightly hazy to sparkling. Guests constantly leave comments about how clean and odor-free the hot tub is. Zero chlorine smell, zero irritation complaints, zero “the water looks gross” messages in the Airbnb chat. That’s huge when you’re trying to keep a 4.9+ rating. A quick side story: my last inflatable hot tub (also bought on Amazon) finally gave up the ghost after I accidentally punctured it while moving patio furniture like an idiot. Ordered a new one, set it up, filled it, and the very first thing I did was dump in these AquaDoc tablets. Water was ready for guests the same day with perfect chemistry. No priming, no waiting a week for a bromine bank to establish like I’ve had with some other brands. It just works. If you have a hot tub at an Airbnb, VRBO, or even just your own backyard and you’re tired of babysitting water chemistry, do yourself a favor and grab this bucket. It’s affordable, lasts forever, dissolves fast, keeps water crystal clear, and is foolproof enough that even my housekeeper can handle it while I’m halfway across the world. 100% recommend – I already have “Subscribe & Save” turned on so I never run out again. Highly, highly satisfied customer!

It arrived quickly, the product is working great, and the price was awesome.

I purchased these as refills for a popular in-line system since they have a smaller diameter, stacking about 8 tablets in the cartridge. Picture on right is after a little over 3 weeks of use. The bromine level remained steady and worked better than the original product in the cartridge. Our hot tub seemed much cleaner visually and smelled better than it ever has. Dial setting 1 for <400 gal. Looking forward to the cost savings with these!

Bromine tablets are great for my spa, and I prefer the larger bucket size for a better value. AquaDoc is a name brand I trust and use often. I refill my tablet floater once a week with 4-5 tablet and it keeps my water fresh looking.

Works well, great price.

These are awesome and last long time before having to add any more to hot tub floater

We use these for our hot tub and it is amazing. Water clarity is perfect and these are easy to use

Love this product. Very straight forward and easy to use when balancing chemicals for your hot tub can be complicated. Dissolves slowly so it releases slowly and evenly. I have been adding 3 tabs to the floater once a week… super easy and works well!
