Clorox® Pool&Spa™ XtraBlue 1” Swimming Pool Chlorinating Tablets, Kills Bacteria & Stops Algae, Perfect for Small Pools (5 LB)

Purchased for our hot tub. Great value. Will purchase again.

Keeps my above ground pool at a good chlorine level and fit my 1 inch dispenser really well.

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.

Very good item, great price and good quality

Great price

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.

The costs savings of using these tablet are immense compared to all the other crap on the market!!!

I crush one of these up and put it in filter housing around randomweave (20um nom.) filter. Keeps Fe-bacteria from developing in downstream fixtures. No taste issues.
