Best pH to dissolve Calcit

[obaltus]

Hello,

I need some advise. I am running a Calc Reator filled with Calcit and I was wondering what was the best pH to dissolve this media?

Thank you, Olivier

I think folks usually use a pH around pH 6.5, but I'd focus on the alkalinity of the effluent and the tank, and not so much the pH of the reactor.

These may help:
