Works as it should

Decent price for a large amount of alkalinity. My only issue with it is that the pail wasn't sealed very well in shipping and a lot of the powder was spilled all over the box that arrived. It was coming out of the box all over my front porch where FedEx left it.

Most Reliable vendor

This is the best product for raising alkalinity. The price is the same as on Doheny’s website, but I get free shipping and earn points with my Prime account and Amazon credit card.
