Sera JG 3 x Reagenz Test

[Marlize01]

Hi all

This may sound very stupid... but this is a first for me.

As per instruction from the pet shop, I need to test my Mg in my tank as I've tested everything except magnesium. He sold me SERA Mg 3 x Reagenz

But I don't have an idea how this tester with the 3 x Mg 15ml bottles work!!!!

Can you please assist????

Ok... So he sold me the wrong box.
