But even in an established tank, Calcium Carbonate will precipitate first on the warmer parts of the tank like the heaters or impeller spindles. The greater the water temperature in a reef the more likely to have Calcium carbonate precipitate. Oolitic sand in the Caribbean forms like underwater rain when surface water temperatures climb.
It never made sense to me either but experience has proven to me that Calcium carbonate is more likely to precipitate at higher water temperatures.
