Having spent the last week dosing my Mg levels from 960 up to 1200 I decided to check my container of fresh salt water and found it to be at 1020 (D&D H2Ocean salt and 200L water made 6 days ago).
However, I've just noticed my Salifert Mg test kit has an expiry date of 'May 2009'.
Might be a daft question but is the expiry date critical?
Cheers
