PH

First of all, thanks to Aleman for the very in depth talk on water at the festival. Very mind boggling, but very interesting nontheless!

I've ordered some gypsum, and I have two kinds of acid (lactic and citric), acid malt, and narrow range ph test strips. So that should be enough for PH correction. :lol: unfortunately the value ph meters only function up to 50c so I'll be unable to see what I actually hit.

So it's as simple as taking a ph reading, adding acid, stirring and testing again?

any simple and easy calculators just for PH?

After that, I don't yet have anything to taste Alkalinity. What should I order?

I'm not that clued up on this stuff. Reading the sticky now.

cheers!

ph strips rob are a waste of time. You need a salifert alkalinity testing kit for alkalinity. Have you had your water analysed yet? There's a bit more to it than just adding gypsum etc If you get an accurate water report try jims beer kits water treatment calc. That's what I use at the moment.

Auto temperature correction on a pH meter only corrects for the effect of temperature on the probes not for the fact the actual pH of the sample changes. So you must cool the sample to 20C.
