86133 pH Up, Spa & Hot Tub Chemical Raises pH, Prevents Corrosion, 2 lbs

Review:This pH Down does exactly what it promises—quickly and effectively balances the pH in my spa water. It’s easy to use, dissolves well, and I noticed a difference right away. As a busy Dad trying to keep our little backyard oasis running smoothly,and keeping the wife happy, I really appreciate how hassle-free this product is. Definitely keeping this on hand!

Best brand of pool products! We use Thai at work for our underwater treadmill tank. Easy to use and minimal smell

My husband loves this. He has ordered it many times for our hot tub. The price is great. It cost a lot less here than at our local pool or hot tub store. I would highly recommend this product.

Product works great and a good size as it doesn't take much to treat a smaller hot tub/spa.

Does what it’s supposed to.

Perfect amount for water treatment! Quick ship!!

This product is great for your hot tub!

I’ve been using this product in my hot tub for years. Works perfect. I use the Ph, Alkalinity and chlorinating granules. This is all that is needed except the floating chlorine tabs!
