or:You're talking about the CCD, Carbonate Compensation Depth, yes? Where the rate of precipitation is balanced by the rate of dissolution. Well, Calcium carbonate is unusual because the lower the temperature the higher the solubility, increasing pressure also increases solubility. In deep oceans dissolution occurs at 4 to 6kms depth.
