Got this to increse the PH levels and it works well putting in the required amount into a 40 degree hot tub and it desolves very quickly. use with the slow dissolving chlorine tablets works well

Pn plus increaser.
Rating: 5 out of 5
I needed to get the water quality in my hot tub right so I watched the YouTube videos on what I needed to do. I bought ph increaser and added it to the water like the instructions on the tub said, after trying and adding it and testing the water the water quality improved to what it should be. It is by adding a little at a time and testing that you can get the ph right 7.2 to 7.4. It is a great product and the price is right,also the delivery was quick.

I tried to fix my spa’s pH levels with the usual cheaper method from the supermarket - after 2 weeks they still weren’t right. I bought this product and used it once and the levels are still perfect after over 4 weeks of use.
