ever since i switch salt, reef crystal... my tank has slowly crashing.. i notice some coral have white spot on them and issue slowly dying.. i thought it might be a bad batch of salt..so i bought red sea brand.. i tested my water everything seem fine except for the carbonate hardness is at 3-4 ..anyone know a way to buff it up back to 8 to 12.. i even try using kalkwasser to drip..over night and hasn't seen any boost yet.. so any advice would be greatful..
