    Hi All am a bit stumped here as I have tested my Mg with three diff kits and these are the results

    Salifert - 1140 tested today (New Kit)
    Tropic Marin - 1310 will have to check again as this one was done on the weekend (Kit a month old)
    Elos - 1300 tested today (kit About 3 months old)

    So has enybody else had this experiance before and wich one would you go with...

    Seeing as the Elos and TM tests are basically the same so I would go with those, a difference of 10ppm between test kits is no concern, but a difference of 200 is, it could be that the Salifert kit is faulty, it is known to happen, even on brand new kits.

    Have had a chat with Scott from Aquarium Depot and he will test the salifert kit on his tank and compair with his kit.
