Vicente Mcdonnell Posted August 6, 2014 Report Share Posted August 6, 2014 Unlike the kh kit's color change, the gh test kit color change from orange to green is way too subtle. Especially on the first 1 - 2 drops. Is there a better way to get a GH reading for the visually challenged? Do any if you struggle with the API gh kit as well?

Subtletanks91 Posted August 6, 2014 Report Share Posted August 6, 2014 I hate liquid tests for this reason. The color changes aren't the best. I'm looking into getting some pen electric test machine things, Quote Link to comment Share on other sites More sharing options...
Vicente Mcdonnell Posted August 6, 2014 Author Report Share Posted August 6, 2014 Is there a digital meter for gh or kh? As far as i know meters only exist for tds, temperature and ph. Quote Link to comment Share on other sites More sharing options...
Subtletanks91 Posted August 6, 2014 Report Share Posted August 6, 2014 They exist for nitrates and such as well. There probably some for gh and kh, or at least conductivity of the water but there most likely lab grade Quote Link to comment Share on other sites More sharing options...
metageologist Posted August 7, 2014 Report Share Posted August 7, 2014 There are field grade instruments the will do real time pH, orp, conductivity, tds, Do and a few other things depending in the probe attached. They are called YSI meters and run about 1200.00 if I remember correctly. Quote Link to comment Share on other sites More sharing options...
