  • epsom salt for raising MG

    I have used MG granulate in my CA reactor,but my reefcrystal sea salt is
    a low level of MG ( I am not sure but about 1000ppm?)
    so I add Seachem MG when changing sea water in a week.
    I heard that there is epsom salt in US.
    I have never heard about this. what is it?

    if epsom salt is a kind of salt(like a word ) Can I put in it with my
    Reefcrystal sea salt?


    I heard many reefers in us use this, and it is not bad.

    epsom salt by itself is a salt name...
    it is Magnesium sulfate heptahydrate

      Is it better than Seachem MG?
      (I think Seachem MG is more expensive than epsom salt)

        Epsom salts in Australia at least 40 times cheaper than the Seachem MG supliment in Australia. I would not add Epsom salts all of the time as it will cause your sulfate levels to rise.

          I order from industral those food grade MgCl and cost me Sg$18.6 per kg only..
          alot cheaper then those marine MgCl

            If your Mg level is low, first check your salinity using an accurate instrument (refractometer is ok, plastic swing arm toys is NOT); too often a Mg problem is due to too low salinity levels. Reef Crystal has good reports of Mg levels.

            Then, use a 10:1 mix (in weight) of, respectively, magnesium chloride and epsom salts, which is a much better additive than epsom salts alone. At least you have a balanced residual of chloride and sulfur.

              Thanks..

              Where can I get Magnesium chloride ?

              How about mixing epsom salt and seachem Mg supplement?

              I think it is better than only epsom salt use...

              and I found some types of epsom salt.. Which is the proper to put in my tank?
