Borax as ph meter calibration fluid question
How much borax per cup of water to make a calibration fluid of 9.2? Randy mentions a link in this article: http://reefkeeping.com/issues/2005-02/rhf/index.php#7 but the link is dead. Thanks in advance

It is 3.80 grams per Liter. This is 9.18 at 25 deg C. So do the conversion from Liters to cups.
