Locally I pay $90 for the 225 bucket, and $50 for the 120g bucket. A store can not sell the salt unless they are an authorized AquaVitro dealer, they need to be certified, that's why you won't find it in a ton of local stores, especially if you don't live near a major city. I'm very grateful for where I live, lol
After my salt mixes overnight I get 0 for phos, 0 for nitrates, 9.5dkh, 420 calcium. Honestly, I haven't tested out of the box in a long time. I stopped testing each time because it was always the same.
