A couple of weeks ago, in a thread I replied to, I mentioned to someone who was scared of muriatic acid, that they could use dry acid instead.
A more veteran poster quickly let me know that dry acid was a big no-no, as there was a problem with sulfates in your pool. I quickly accepted this as me being wrong and moved on.
However, I was just looking at Pool school for something else to help a poster with, and noticed that it says in recommended chemicals that you can use dry acid, with no warning of sulfates.
So what is the correct answer? And should pool school be updated?
