Hi all, I am trying to get myself some PH Test Strips.
There are broad value strips and narrower ones. either 1-14 or 2-5 for example.
Should I get various in different ranges for .5/.25 accuracy or are the 1-14 just enough?
Also I am interested in testing the following formulas.
What ranges would I need? 4-6 + 8-14?
Can I be sure that the solutions work just by their PH?
Can I be sure the solutions DO NOT work just by their PH?
-Maco ECOFUX(Neutral ph?)
-Adox Fix Adofix
Thanks for any INFO!
