product called pH Down

[Johnny B]

I have a product called pH Down.
Active ingredient sodium Bisulfate 93.2%
Other ingredients 6.8%

Must be old, before my TFP days. I’d like to get it off my shelf.
Any reason I shouldn’t use it to lower my pH when that is indicated?
We don’t like to have it on hand for some other reason, right?

Thanks

It's just dry acid. Nothing wrong with it except maybe the price relative to MA.
