XtraBlue 3” Chlorinating Tablets

I like that each comes wrapped separately. None broken in pieces. Total of 10 came in the 5-lb size container. These seem to work the best in our round above ground pool. 1 weekly tablet for 18ft x 4ft high pool. I also add 1 arm & hammer pool ph stabilizer tablet with the chlorine tablet floaty to keep ph great.. and shock every 2 weeks.. sooooo easy! Testing is always perfect! Had my pool 16 years now.

Box arrived sealed. Chlorine tablets are very strong I suggest opening outside. They fit nicely in the KingSom dispenser. Designed for algae removal and maintenance. Suggest brushing walls of pool and steps to accelerate chlorinating and promote even dispensing. I can’t address chemical free aspect but even within a few hours I can see the chlorine is having a positive affect. Container does reseal but does not lock. I suggest placing in a safe place to keep away from children.

I use these in my above-ground pool and they’ve done a good job keeping the chlorine level up between treatments. Easy to use in a floater and dissolve at a steady rate. No complaints.

This product works great for keeping your chlorine levels where they should be and helps keep your water clean and free of algae. One tablet last about 2 weeks which is good. I use a float that holds about 3 of them so I set it and forget it. My only issue with these tablets is that they can’t be used the next year. Seems like they lose their effectiveness after awhile. I had 2 tablets left over from the previous year, used it and they literally only lasted like 2 days. So I knew I had to buy more.

Our pool guy recommended getting these to have on hand for him when he comes to clean the pool. He’s the certified pro so I’m going to keep buying them. I don’t know if they do anything to color the water as we have a large pool but they do what he needs them to do to keep the water chemicals in balance.

We love these tablets - bought these the last couple of years! Very good price too!

This is the only tablet chlorine I will purchase for my South Florida pool

This is the worst product I have ever used after having a pool most my life, could not get my pool water right. It's like whatever is in these tablets doesn't allow the chlorine to work, so much chlorine in the water we can't swim, but can't get rid of the algae. The Pool Store ended up telling me I just needed to empty my pool and start over ($200 more dollars) What a complete waste of money. The water constantly looks cloudy, algae floating, growing in my filters and sidewalls. Seriously a $8 gallon of bleach would be better than this product that I'm stuck with.

item received damaged most of the pieces are broken and powder came out of the box and the package (toxic material came out and spread in all the my entrance need compensation as i take pictures for every thing

All the tablets were destroyed… cost a lot of money for products isn’t in good shape this isn’t nice !
