King Technology/ SPA Frog Cartridge Kit (2523)

Set it and forget it. Love this chlorine delivery system

so expensive wish I could find another option

Been using this floating system on same hot tub for 12 years. Water is always pristine. Very simple system.

Keeps my spa water sparkling!!

We have a 400gallon hot tub and use these cartridges. These keep our hot tub clean clear and scum free, must be replaced every few months. The bromine runs out faster than the natural enzyme. Easy to use.

The frog products are easy to use and saves money chlorine.

I LOVE this product. After remembering how much of a chore it used to be to regulate water in a swimming pool I was reluctant to even get a hot tub. Using this product was the answer. Snap the two cartridges into the holder, Twist to choose the recommended number, and then drop them into the hot tub. Done. No, really. That's all there is to it! It keeps the water crystal clear. Day after day I can use the hot tub without thinking about it. When the yellow cartridge is empty it flips over and floats on its side which tells me to change the cartridge. The yellow cartridge lasts for a few weeks and the blue for a few months. One kit of a blue and three yellow should last the summer. This product is more expensive than simple tablets but it is well worth the price to have clean, clear water without constantly having to test and adjust chemicals.

This is the best for your hot tub. Put them in the frog house and that’s it! Super easy and keeps the water clean year round!
