    Tablets, take to and check again in 4 days...

    Posted by D. Polister on Sep 1 2020

    Large container of 1 inch chlorine tablets. Our small pool, around 1000 gallons, takes 2 tablets in the floater to maintain the proper chlorine level. It last for about 4 days. I have noticed that a lot of it will depend on how much sun shine your pool receives. If out in full sun, you may need more tabs to maintain levels. The sun will breakdown chlorine fairly fast. When we use a canopy over the pool, the chlorine lasts for days.

    I throw 3-4 in my floating dispenser at a time ...

    I throw 3-4 in my floating dispenser at a time and they last about a week. These have worked well as my pool is still sparkling clean with no issues with algae or scum.

    Just what my hot tub needed

    Posted by jeepchic on Jul 2 2020

    I am reviewing the Kem tek chlorine tsblets. These are perfect for my hot tub. I just load up floating chlorine dispenser and let it float away in my hot tub. It works perfectly for keeping the water clear and disinfected. Those are one inch tablets. Make sure when using to avoid breathing in any of the dust when you are placing in your dispenser. Thanks for a great product at a great price!
