Requires multiple doses
Purchased for my hot tub to increase very low water hardness readings. Has taken typically 3 doses over the course of a few days (following dosing directions) to get to even the lowest reading on test strips. Considering trying a liquid product, I don’t know if there would be any difference.

Key to keeping corrosion in check
Great product. Hardness is very important in your pool or spa. Too much and you get a lot of buildup. Not enough and things get eaten up. Just the right balance keeps a light coating on the internals keeping them safe from corrosion for a long time. I found this product to dissolve well and adjusted to proper levels. That’s for the great product!

It didn't raise my ppm at all even after using the whole bottle for my 500 galhottub
Don't purchase this product thinking this will raise your ppm in your hot tub. I used the entire bottle and it didn't raise my ppm at all for my 500 gallon hotub.
