Works great keeping my hot tub tip top shape.

My hot tub has no complaints and neither does my skin. It works as it should and doesn't seem to be causing any issues. I say buy

This item is well represented in the photos and description. It has directions printed on the canister and they seem to be accurate. I obsess over the water balance in our spa. A well balanced spa will increase the longevity of the spa and all of its components and also feels better when soaking. This is a smaller canister than what I usually use but it’s also easier to handle when measuring and dosing the product. It’s a good product for a fair price.

This product works excellent to get a perfectly balanced test strip for our hot tub! It stands out above the rest with the very clear and direct instructions! Will buy again!

I used this when I refilled my inflatable hot tub a few weeks ago. My water seems to come out of the tap with a low ph. I added this stuff, cycled it, and checked the next day and the ph was within normal range. What else do you need? Would buy it again.

Just as described!My hot tubs water is perfectly balanced.

I am considered a beginner at Spa maintenance so not sure if I’m the best person to review this product. It seems that if I follow the instructions completely and closely that I did achieve the chemical result I was looking for. So I’d have to say this purchase was successful.
