Great product effective and easy to use in my filter

I’ve been using these sticks for over 3 years. I was tired of all the chemicals, constantly adding bromine, Ph up, Ph down. Bath tub rings……. Every darn weekend. Kids get in there and now I gotta shock it. I have a 500 gallon hot tub. Put one of the sticks in your filter hole. Throw 4 bromine tabs in your floater and a 1/2 cup of Leisure Time Replenish. That activates the minerals in the stick. You’re good for 3-4 months. We use our tub 1-2 times a week during the winter. PH stays perfect. Water so clear you can see the dirt from your kids on the bottom of the tub. When the water starts to turn a bit, swap out for a new stick and activate it. You’re good for a couple more months. No smell, no work, no testing strips, fits right into any filter. Do it. No regrets in over 3 years. Cheaper than any bottle of chemicals.

They work great

Works great in my hot tub
