If you are looking for a reliable product to keep your spa or hot tub clean and safe, this sanitizer is a solid choice. We’ve been using it for a few months, and we are very impressed with the results. It really does start sanitizing quickly—within the promised 15-30 minutes of application, which is great when you want to use the tub soon after treatment. The water has remained crystal clear. It effectively destroys organic contaminants and helps control algae growth, making maintenance easy.

great product works well water very clear from day 1

Sanitizer for my hot tub Works well, the water is always nice and clear. I find the price keeps going up every time I order.

I love it! Great product! Keeps my hot tubs always testing perfect and sparkly crystal clean and clear! Great value! I'd never buy another brand. It's so much cheaper on here than in a store.

much better then the product sold from my hot tub store
