Argonite ?

I got a plant near me, I know someone working there.

Looking at the MSDS sheet, Argonite/Limestone/Calcium Carbonate/Fluxstone are all the same.

Limestone is the most important and abundant sedimentary rock and is formed by the compaction of the remains of coral animals and plants on the bottoms of oceans around the world. Limestone is composed of the mineral calcite (calcium carbonate) and/or the mineral dolomite (calcium and magnesium carbonate) along with small amounts of other minerals. There are three distinct types of limestone which are defined by their magnesium carbonate (MgCO3) concentrations:

Dolomitic limestone consists of 35 to 46% magnesium carbonate.

Magnesian limestone consists of 5 to 35% magnesium carbonate.

High calcium limestone contains less than 5% magnesium carbonate.


If I can get access to some, I should take the High Calcium limestone?

Don't do it. Who knows what other contaminates might be in there. There are also many different types of limestone. Technically limestone does not equal aragonite, and as far as I understand it most limestones are primarily calcite based and contain little to no aragonite.

I was always told......"When in doubt leave it out"!

Well the do chemical grade limestone, I guess there purity is high.
