is there an obvious result when your R-004 reagent is no longer accurate? I just tested my PH and the result is a fluorescent pink. Like off the chart pink. It can’t be right. Is this a sign my reagent is no good? It is 2 seasons old so starting my 3rd season with it. There is no best before date on the bottle.
