Review on 🔍 Accurate Measurement Made Easy: Salifert Magnesium (MG) Test Kit by Shannon Williams

I previously bought a NYOS mg test kit which had a fairly low expiry date in my tank and showed low mg levels. I then checked my salt with Nyos and it reported low mg again. So I bought a new Red Sea Pro salt and again it showed less than 1100ppm. I received my Salifert mg test kit and my tank reads over 1600ppm and I know it must be true because I've poured almost a whole bottle of Red Sea mg into my 25g tank in the last 2 weeks , put Nyos due to the test of lower quality. I have used the Salifert mg test kit before and thought I would give Nyos a shot but that was a big mistake.
