Costco Clorox Pool & Spa XtraBlue 3″ Chlorinating Tabs
This bucket comes with approximately 80 3 inch tablets. It’s the 40 pound value size. I think Costco used to sell a 50 pound bucket in the past, but now it’s 40 lbs. Costco doesn’t sell this online probably because of the shipping, so it’s best to get it in store. If you can’t find it in store or you want to check out some of the other highly rated 3 inch tablets, make sure to check out the following links. There are a few other brands besides Clorox & they are very HIGHLY RATED. Check out the links here…….

I went to Costco today, and they had the 37.5 lb of the hth tablets for $165 and 40lb of Clorox tablets for $189.
Yes, the price has increased quite a bit from last year, but this is still the cheapest I’ve been able to find.
Ya. The price increase is pretty extreme. I know it’s hitting a lot of people hard. Glad to know it’s still the cheapest around
Check these prices. Lower cost plus 10 lbs more.

Thanks for the heads up John. I haven’t seen these Chlorine Tabs at any of my Costco’s in a while now.
RIDICULOUS!! HIGHWAY ROBBERY EVERYWHERE YOU GO!! ;-(((
Sorry to hear Joe! Maybe someone who knows more can explain why the price of these tablets has more than doubled. It seems egregious, but I’m sure there is a reason why. It seems to be hitting all the pool maintenance workers hard because I keep getting emails about it
Okay so I work in the pool maintenance department I am a certified pool technician I have my own route I know for a fact that’s last year one of the biggest producers of the Tricor tablets there whole plant burned down to the ground due to that since for about a year-and-a-half now the price of a chlorine tablet had more than doubled which in turn is making demand for liquid chlorine High so the price of liquid chlorine has also doubled anyways it’s supposed to be in the process of being rebuilt and should be rebuilt by the end of the year but other pool professionals are predicting that the price for a 50 lb bucket of tablets will hit anywhere between 250 to 300 by the end of summer
Wow! Thanks so much for the insight. I just assumed it had to do with inflation (which is probably also part of the problem). Thanks for the heads up. sorry about the increased costs. That’s gotta be tough to explain to every customer
I saw those coming out early this morning. The price went up to 189.99. Holy crazy!!! (Location, San Dimas CA)
No way! I haven’t seen them at my Costco yet but I will be keeping my eye out. That is more than double for the price jump! Crazy! Thanks for the heads up
Yeah. I just saw it at Cypress Costco $189.99 and limited stock too. I think it will keep this price for awhile since everything is oos.
OK. Thanks for the heads up. I have not seen this at any Costco’s near me as of yet. I’ve keeping my eyes out though. Thanks for the heads up
When are these going to be available in Long Island?
Not sure. I haven’t seen these at ANY Costco this year so far. I keep checking. I’ll post as soon as I see them
Same price at $ 189.99 at Scottsdale , AZ
Wow! I still haven’t seen these in stock for a while at my Costco’s (Northern CA). That is such a large price increase! Hopefully it’s just temporary & will come down in the next few months. I’ve gotten a lot of messages from pool maintenance workers asking about this.
When will you have the 3″ tablets
These usually come out in the Spring when everyone starts to get their pools ready. I’ll keep my eye out and post when I see them
Tri-chlor tablets contain nearly 50% cynauric acid. So yes they will cause your cya to go up. If you have a sand filter and backwash propertly this will help mitigate the build up. You want some cya as it protects the sun from burning out the chlorine. If you solely are going to use shock as your sanitizer you will need to add it several times a week. Just test it to see if the chlorine is low. Good advice my man.
Thanks for the tips Zach. Appreciate you stopping by. Hopefully that helps out a few people with their pool maintenance
Yes its true tabs have stabilizer, buts it’s so minuscule that if you regularly use your tablets you wont need to drain for at least 3-4 years which in my opinion is long enough to go with the same water regardless of the cya.
Thanks again for chiming in Elijah
Can shock be used in the pool weekly if there is no supply of chlorine available?
Sorry Joanne. I am no expert when it comes to pool maintenance. Hopefully someone reading this can chime in with their experience.
Hey Joanne, it’s smart to do around 1lb of shock per 10k gal of water once a week. You would also want to do abt 2-3 tabs once a week as well. As tabs just maintain the level while shock is what actually increases the level so that the tabs can keep it maintained.
Thanks for the tips Elijah! Hopefully that is able to help out a few people who might be reading this. Appreciate it
I recently tried to pickup chlorine tablets at my local Costco and learned the shortage is related to a fire at the plant that makes the tabs. True or not I don’t know.
While hunting for a replacement a Google search turned up comments on a pool forum where the pros hang out. Seems the consensus is you don’t want to use to chlorine tabs (liquid chlorine is preferred) and you especially don’t want to use a ‘blue‘ pool product as that is code word for copper.
Tabs have stabilizers that will raise your CYA (cyanuric acid) levels. This helps chlorine last but throws the chemical balance off in the pool such that it is often necessary to drain and refill the pool to remedy.
Copper is a problematic heavy metal to add to pools. I personally don’t want copper in my pool. Do your own research from these pointers, but I’m getting off the Clorox Blue train now.
Well thanks for the information Jean. I can’t verify that information, but it gives us something to research & maybe ask questions about. One could always ask their pool maintenance person when they swing by. I appreciate you sharing that information.
The shortage is real. It was announced in the news.
The manufacturer is located in Louisiana after a hurricane last year It suffered a fire. They’re hoping to resume Production next year 2022.
With covid-19 production will be slow.
Thanks for the heads up Jasmine. I haven’t seen it in stock at Costco since early summer. Good to know. You’re right about COVID slowing everything down.
Yes its true tabs have stabilizer, buts it’s so minuscule that if you regularly use your tablets you wont need to drain for at least 3-4 years which in my opinion is long enough to go with the same water regardless of the cya.
Thanks Elijah
do you have the chlorox 3″ chlorine tablets for pools in stock at warehouse or do I need to order them on line item # 958894
They are in stock in the local Costco’s near me. I live in Northern California. You may want to visit your local Costco first & check the item number to see if they have it, will have it, or have it nearby. It will save you on shipping. Let me know if you end up finding it
I’m in Ohio and we cannot find the chlorine tablets so are you able to get them at all? There
Yes, I have seen these in stock at all he Costco’s around me. Summer is upon us & these have been in and out of stock at my Costco’s. When they first hit the shelves they were gone within days, but now they seem to be in stock a little more often. I would grab the item number & see if you can ask a Costco employee when they will be in stock. Hope that helps
Looking for a store near me to buy the clorox xtrablue chlorine tablets advertised above. My zip is 11934. Can’t find it via local web page.
Thanks in advance!

Hi Gene. Costco doesn’t have an inventory tracker online. You would need to call your local Costco to see if they stock these Chlorine Tablets. It doesn’t look like there is a Costco on Long Island so I would call the few Costco’s near you and see if they stock them. Wouldn’t want to waste a trip if they’re not in stock. They should be able to help you. Hope that helps
There’s a Costco in Commack
Awesome! Thanks for the heads up Emmanuel. It’s nice to helps out fellow Costco Fan’s. I can’t tell you how many times I’ve gone back to a specific Costco only to find a product gone! It’s amazing how much inventory they move. Thanks for stopping by
My Costco in the NY area had a different brand a month or so ago, maybe HTH. Pretty sure they sold out of that and the shock very quickly due to chlorine shortages.
Also, on a side note these Clorox brand chlorines have high amounts of stabilizers which can build up and cause problems which will require draininng/refilling water to dilute.
I saw that HTH at the store also. I’m kicking myself for not snapping some pictures of it because it was right next to this Chlorine. Thanks for the tips on Chlorine usage. That’s good to know
