FROG Replacement Chlorine Cartridges for Use with Flippin’ FROG Floating Sanitizer System - Prefilled Cartridges Support Easy Pool Maintenance and Cleaner & Clearer Water - 1 Pack

Honestly best purchase I ever made for my above ground pool . No need to measure chemicals or spend money on all different products. I have a 22 inch above ground pool. I only used this product this summer and some days forgot to run the filter . Still clear blue water. I was worried it would stain the liner. I just replaced this year but no issues at all . It does exactly as described flips over when it times for refill . I had to refill every 3-4 weeks. Sometimes I would see some left over product and would just add some string and left it to float by the skimmer . Didn't want to waste any product.

The Flippin Frog is all I need to care for our pool. I recommend anyone with a pool purchase one. The replacement cartridges are easy to replace and last a long time.

I absolutely love this chlorine system! I've been using it for 2 years now and pool stays perfect!

I love this system for our small above ground pool. Very easy to use and keeps the pool water clean and clear.

love these

perfect for keeping the pool clear and clean without much effort

I use the Frog system in my hot tub and reduce my use of other chemicals by 45%

kept my pool clean amd clear thus far, even after heavy rain falls. loving this product.

Looser fit than original cartridge. Slight algae growth just days after replacing cartridge. Needed to shock pool more frequently to maintain clean water.

Doesn't last a month - pretty expensive but does the job.
