I've had trouble inducing Mg deficicency with reg water changes with
most tap water.

You can add dolomite if it's for Mg/Ca and KH(CO3).

Thanks again Tom. I found that the Aragonite (crushed coral) maintained my
PH better than the lawn lime (dolomite). So I guess that answers my question
about the Magnesium. I've still got 50 lbs of lawn lime, if anyone needs
their lawn done.


MgCa(CO3)2
Get fine ground, this will dissolve better.

Most folks use baking soda for ther KH. CaCl2(pool stores often carry
it) and MgSO4(Epsom salt) for Ca and Mg.

These dissolve immediately.
