Number 1 in Service Frog Replacement Smart Chlor Cartridges 3 Pack and Hot Tub Water Balance Guide

The Frog Ease system works and is is easy to deal with. I usually change these out at the first of each month and change out the top part of the system every quarter when I drain and refill the tub. It is an easy system to use and the subscription option keeps me from having to think about it.

This product is great, I've been using it for 2 yrs now. It came with my hot tub package originally.The only problem I've had is twisting the top on and off. Maybe because I have long nails!I only have to change this every 3 - 4 mos. instead of every day or week.

Love that I can just drop this in after I set it where I want and it takes the work out of sanitizing the spa. Water stays clean and chlorinated. When it flips you know you need to replace the cartridge.

This Frog Ease system works pretty well in my hot tub. It is easy to use for sure. I have two gripes though. First, I don't always get the amount of time stated on the box out of these cartridges. Second, I can get this same box of cartridges at my local hot tub supplier--who is unfortunately a pretty time consuming drive for me, and not open on Sundays--for $10.00 less than I paid for them on Amazon. Maybe it's worth the drive.

Works great

Easy to use

This is great for very easy management of hot tub! I check on hot tub once a week and don’t have to do anything (we hardly use it, but it is ready when we do)! You can leave for vacation and come back home to a crystal clear hot tub, rather then a stinky murky mess you have to empty and start over again (or shock and wait for a possible clean up in a week or so),..

Been using this for a year and very happy
