, that is not that low. NSW
mag is about 1200ppm. One of the theories about magnesium is that it is a buffer for your CA
. If you are running a normal ALK
and your CA
refuses to raise to where it should be...you should test your Mag, it is most likely low and the opposite is also true. There is no doubt that Mag is important, otherwise it would not be found in such high concentration in Seawater. What you can use to raise it...There are many Magnesium supplaments on the market today, I used to use the one by Kent. If you'll go to www.ozreef.org
there used to be a recipe for a DIY mag supplament that used epsom salt.
