Red Sea Mg Ca Kh frustration
I’ve been using this test kit for the last couple of weeks and I really do find it inconsistent in results and very fiddly to use. The Mg I’ve followed to the rule. 15 secs between drops, 1 minute for the 5 drops getting a result of 1500. Re do the test but for 20 secs and I get a different result, this time 1400. When I compare to the likes of JBL and Salifert it’s always 50:60 points higher. Ca not quite so bad but is always 25 lower than Salifert and 40 higher than JBL. KH I have to run 3 tests as this also is inconsistent by giving high results. I have to do 3 tests for each just to get a repeat result. Very disappointing!!!!! and is affecting my dosing regime because the results cannot be relied upon. Does anyone else have this experience.
