Argonite slowly disolves releasing calcium and carbonates into your water. If you ever wanted to keep an African Cichid tank, use crushed coral for a substrate and you would have PH 8+ and alk approx 14 without any other additives. Saltwater is a lot slower in reaction but your sandbed will shrink in time.
If you set your PH in your calcium reactor to 8.0 - 8.4 ( typical reef tank ) how much of the argonite do you think will dissolve ?
Cheers
