most accurate magnesium test kits

[gatekeeperdi]

Hi, I was wondering what people thought were the most accurate and straight forward magnesium test kits were. I've been using the red sea pro magnesium test kit but it always seems to read higher than if I get it checked at my LFS.
Any suggestions and reasons for preferences would be really appreciated.
Thanks Di

I had the same problem with the red sea magnesium pro test kit until I watched the youtube video how to do it correctly. Turns out the instruction card is misleading when it shows the the bottle shaking for 60 seconds its really a quick shake and let sit for 60 seconds. Hope that helps.

I prefer the salifert. I've tried elos and got very inconsistent results. Red sea I've always hear tests high
