bcjm January 25, 2008 Share January 25, 2008 Can someone comment on the following? "Oyster Shell is nothing but Calcium Carbonate and Magnesium Carbonate. When the Oyster shell dissolves due to the presence of acid water, it liberates Calcium, Magnesium, and Carbonates. These mineral liberations increase the hardness of the water (contributing nothing to Buffering capacity) and the Carbonates increase the Alkalinity. Thus, the pH is stabilized. Crushed Coral is Calcium Carbonate and Magnesium Carbonate but also contains a central structural molecule of Calcium Hydroxy-appetite. (I didn't name the stuff.) The significance of this is that when the crushed coral dissolves, it leaves behind the insoluble Calcium Hydroxy-appetite which is not a contributor to pH stability. While crushed oyster shell dissolves and vanishes, letting you know when to add more, the crushed coral remains, looking good but doing nothing."

Grav January 26, 2008 Share January 26, 2008 I'd consider the source. For example, if RHF wrote it, I'd put $ on it, and then I'd buy some oyster shell with the winnings. Link to comment Share on other sites More sharing options...
