Aragonite locally ?

[allincuddy]

The only real way to dissolve the argonite in your tank, is to have a PH level so low that it would be rather difficult to grow anything in the tank. I think you would need a PH level of 7.5 for the argonite to disolve enough to cause an impact.
Might be wrong, but ?

Can't comment where to find in bulk locally but calcium based sand definitely dissolves with normal tank pH. In my 75g, would need to add a layer every few months as would start seeing my LR supports.
