As the title says, I dosed seachem calcium and somehow my alk spiked from 9.2 to 10.2 in 5 minutes or less. Why would that happen? Alk was supposed to go down when dosing cal. This spiked caused all my corals (LPs and mushrooms) to close up very tightly. I’m now worried I may lose some or all cause of this. Is there a chance for my corals?
