| | Nutrafin Vs Elos KH Test Kits
My Nutrafin Kh test kit expires Jan. 2017 and the Elos test kit is brand new. So I tested my tank water and got results that were far apart.
The Nutrafin kit test at 2.8 KH and the Elos kit test at 4.5 KH. Has anyone tried two different KH test kits and got similar results?
My town's yearly water reports show a low of 1.28 to a high of 4.2 KH for the last four years. Now I cannot tell which of these two kits is more accurate. Your thoughts?
I would like to know if there is a way to make up a solution with a known KH so that I can test these kits to see which is most accurate.
