What was the answer?
Even if it works, why do people always try to avoid buying ph down, its so cheap. I've heard lemon juice, battery acid, pool chemicals and all kinds of non sense to ph down the water. I mean a liter is only $12?!

theres no ph down kit over here bro. I would love tho buy real ph down kit lol !! ebay takes too long so as amazon ..However that prodcut should be work but not super stable.
