I've been trying to switch from B-ionic to kalk for my 90G (with a light coral load but nuisance-level coraline), and my Ca also drops to about 330, forcing me to bring it back up with B-ionic (to about 380). I was wondering where in heck all the kalk was going - I've also tried using vinegar, following ReefCental recipes, but the kalk still has been inadequate to maintain Ca. I have suspected the coraline was sucking it up, but haven't worried about it too much as my few corals (monti, plate, hammer, one acro frag) have still been growing.
