Fill your feeder or floater with tablets and adjust output to bring chlorine to 1 – 4 ppm, test and refill as needed to maintain adequate sanitization. For skimmer application, add 2 tablets per 10,000 gallons to bring chlorine to 1 – 4 ppm, then add more tablets as needed to maintain adequate sanitization.

Maintain a regular cleaning regimen. Skim water surface, brush walls, vacuum and empty skimmer baskets at least once per week. Download the Clorox® Pool app on the Apple App Store or Google Play for expert water analysis and product and dosage recommendations.

Long lasting tablets!

After receiving the 5 lb. bucket sample of the Clorox Pool & Spa XtraBlue+ Chlorinating tablets, I loaded 3 into my floater. These tablets lasted almost a week! Previous tablets I had purchased never lasted more than 4 days. Definitely will purchase going forward.

Clorox blue chlorinating tabs are great to use.

This keeps my pool sparking clean, and it’s very easy to use. I put it in my chlorinator and my pool stays clean. This is an excellent product to keep the pool clear. It stops algae, and kills bacteria

Clear, blue, easy

I just drop one of these in a floating dispenser and kick back in style while the Clorox Xtra Blue Chlorinating tablets do all the work keeping my pools Xtra clear. They are pretty long lasting and help when the sun is beating down on the pool trying to evaporate all the chems I put in the water.

Chlorox Extra Blue 3″ Chlorinating Tabs

Hi. My name is Pat and I am 72 years old. I own and maintain a pool in Fl and have been doing so for 23 years. I am not a pool maintenance expert, but over the years, with the help of Clorox products, i have been able to keep my pool crystal clear, algae free and at safe chemical levels for all who swim in my pool. The extra Blue 3″ Clorinating tablets allow me to have sparkling water and keep it from having algae. The product works fantastic and is especially great during rainy season because it continues to chlorinate the water and kill algae. I am unable to lift the heavy jugs of chlorine, so these tablets are so easy for me to use. I have been using this product ever since I moved to Florida and have always had excellent results. I highly recommend it.

As good as expected

Clorox 2 in chlorine tablets? Yeah, they do the job alright. Toss ’em in the pool, and they keep the water clear, just like they’re supposed to. No fuss, no muss. It’s what you want when you’re looking to swim, not scrub tiles all day. Good stuff for regular folks who just want a clean pool without any hassle.

Easy Pool Chlorine Addition

For years now I have been using the Clorox Pool & SPA XtraBlue 3” Chlorinating Tablets. The ability of dropping the tablets into my inline chlorinator with little fuss makes pool maintenance easy. The fact that they have long-lasting sunlight protection helps keep a pool clean and algae free in very sunny Southwest Florida. They are slow dissolving and 2 tablets helps maintain my chlorine levels at acceptable ranges. A lot easier than adding liquid chlorine. More time to float around and enjoy pristine clear water.

Slightly better than the others

I was quite impressed by the XtraBlue+™ Chlorinating Tablets. They have a few added ingredients that help with controlling everyday algae with the algaecide and they have a clarifier included which helps keep my water at it clearest and best looking ever. These additives put the tabs at the top of my list. I fill my in line chlorinator feeder with several tabs and I am set for several weeks of crystal clear water that is free of contaminants.

Clorox Pool Tablets keep your pool sparkling clear

Clorox Pool and Spa Chlorinating tablets are the only tablets I will use in my above ground pool. It keeps the water crystal clear, easy to use and seems to last a reasonably long time. We have an 18 ft round above ground pool which I have maintained for the past 5 years. Other tablets just don’t seem to work as well and desolve at a faster rate. These tablets are a bargain and are so easy to use. I just put them into the chlorinator and forget it. After checking my chemical levels, everything is where it should be. I am located in Louisa, VA and I would and have recommended Clorox Pool and Spa tablets to friends.
