Believe it or not the comercial food growers use battery acid. Yes sulfuric acid from the car parts store is the strongest PH down. Not sure about PH up but I have used sulfuric acid for down. Very strong but good.
Best bet is to get some GH PH up or down.
aye it's what we have always used and works np ..... the GH that is :thumbsup:
