That is a good question. I've not been in that spot in 15 years. When I lived elswhere, we had high really high pH water and we're trying to maintain water gardens. We installed an injector and concentrate tank and our compound was powdered citric acid.
I don't remember the details on rates or if that's the best, but that's what we did.
