Haha, you and test kits!
How many times have you used the RS kit so far? The Red Sea Mg kit is really finicky - I won't buy it again. That said, I can get the same reading from Salifert as Red Sea, but those first 5 drops in the RS kit
need to be done 15 seconds apart. Stupid.
I'd dismiss the old kit results because now that I use test kits multiple times everyday and they only last me a couple months maximum, I'm finding new kits match up with "old" kits. I've come to the conclusion that older kits start wandering quicker than we might expect. Looking back through 5 years of test result journals anecdotally confirms this suspicion.
I wouldn't care much between the two remaining results - both are above NSW Mg level.
