Adjusting ph


New Member
I am in a pinch and need to lower ph immediately and have no access to ph down until tomorrow. I read that vinegar can be used to lower the ph but I don't know how much I will need. I need to lower the ph of the water in my 20 gallon hydro setup
It's impossible to say exactly without knowing the PH of the water your starting with and how "hard" it is. Do you have a meter?
