Review: Follow the instructions and it works. - Had a very acid pool below 6.8. Put in 1 kg of powder and left the pump circulate. Tested and the water was now on 6.8. Added another 600 gms and we were at 7.6 on the PH test perfect.
Review: A little bit goes a long long way - Good value for money. Don't need much for a 12ft Pool. Works quickly. There's a little bit of maths involved but I would always err on the side of less because it is easier to add more than to decrease the pH.
