Chlorine Granules for Hot Tub & Spa, Quick-Dissolving Chlorinating Concentrate Disinfectant & Oxidizer, Pool Sanitizer & Shock Treatment for Clean Water, Sodium Dichlor Powder, 2 lbs

After using this according to instructions, our spa water started bleaching our towels, clothes etc.

Wow! I didn't notice this was the 2lbs one. Thought it was a 4lbs one for that price. I used to pay $18 for this in the past. Times have changed.

This product is exactly what I expected.

These work amazing!! Great product

Great stuff. Really pure and doesn’t leave my spa smelling and feeling funky from a bunch inert ingredients. I use less of this than I do of other brands and it works better. The chlorine odor is also super mild. I’ve bought all of the chlorine brands and like this one best.

I will always buy from amazon, Hot tub things, from now on. So much better than chemicals from the hot tub stores

These chlorine granules are easy to use and work great in our families hot tub.

The product works great. Have used this now for 2 months for our home hot tub. I will continue to use.
