Re: Potassium sulfate any good to use?
Anything with sulfate in it is going to be acidic and thereby lower the pH. I have been using the same pH meter I bought from HD for almost 20 years now, and it's still as reliable as the day I bought it. My research demands accurate results, and that meter is accurate. I won't recommend things I don't use myself.
