salifert. quick and simple and has been around for years
I use Hannah for alk alk and cal. nitrate I just need a simple color test.It’s it as good as Hanna?
Easy is what we like. The easier it is the more frequent you get it done...You might give the NYOS a shot. People like it because the coloration, which is pale yellow to dark orange, is much easier to read the results than the purples that the other test kits have. The breakpoints on mine are 0, 1, 3, 5, 12, 25, 40, 65, 95 and 160.
Easy
