Munkii Posted April 12, 2013 Report Share Posted April 12, 2013 Hi all, sorry for the possibly stupid question. I recently acquired a glass CO2 drop tester, but the instructions that came with it are all in Chinese. I understand that it works by measuring the pH of the water in the little ball at the end. So my question is, do I need to make sure the water I put into the ball is perfectly pH neutral? I know my tap water has a pH of 7.5 and I am worried this will effect my CO2 reading. Thanks in advance! Quote Link to comment Share on other sites More sharing options...

Munkii Posted April 12, 2013 Author Report Share Posted April 12, 2013 You need to use 4DKH water in your drop checker. Thanks for the tip! I assume that means I need to pick up a hardness test kit at Hollywood this weekend? Quote Link to comment Share on other sites More sharing options...
SamH Posted April 12, 2013 Report Share Posted April 12, 2013 I don't think HFF sell 4DKH water, the easiest way to make your own would be adding baking soda to distilled water. Google for the recipe. Quote Link to comment Share on other sites More sharing options...
