I recently swapped out a couple of pieces of CaribSea Life rock in my 9 month old tank...within 5 days, my ALK has dropped from low 8s to mid 7s. It is held very consistent with a Trident....never moves a whole lot. Nothing else has changed. The trident is dosing a TON more ALK solution trying to keep up. Will the addition of a couple of pieces or rock absorb ALK? I swapped out roughly 1/15th of the display rock.
