FROG @Ease Replacement SmartChlor Cartridge for use with Hot Tub FROG @Ease Floating System - Hot Tub Sanitizer System Supports Less Chlorine Use - 3 Pack

I started using the FROG @Ease SmartChlor cartridges to simplify hot tub maintenance, and they've made a noticeable difference. The water stays clear and feels softer, and I don't have to constantly monitor chlorine levels. The cartridge flips over when it's time for a replacement, which is a helpful reminder.​While the cartridges aren't the cheapest option, the convenience and consistent water quality make them worthwhile. They typically last around 3-4 weeks, depending on usage. Overall, they've made hot tub care much more manageable

We have consistently been using these in our hot tub and love how easy to use and safe for the kids to be around!

This is the best thing for keeping my hot tub, clean and fresh. Very easy to use so drop it in and forget it!

Order was easy, shipping was fast. Use this product in my hot tube, with the number settings I'm able to make them last almost 2 months, which is a great value and my water stays fresh

This system works well without that nasty chlorine smell everyone hates but sometimes it doesn't flip over as it's supposed to when its chemicals are depleted. Would still recommend.

We have been using the frog system for several years in our hot tub. It's perfect we set it to 2-3 depending on chlorine need and let it go. Checking levels it maintains very well and other than changing filters there is little hassle keeping the hot tub water levels good.

The product was delivered a little while later. I've been using these cartridges for as long as I have owned a hot tub (7 yrs). It just floats in the tub and keeps it clean. I don't have to do anything.

Frog Ease makes hot tub maintenance easy! Highly recommend!
