A couple nights ago I accidentally hit the on button on my Apex for Kalk stirring instead of auto. It ran like that over night. Normally I put 4L into a 132g over 12 hours. I had a safety rule that if my PH was at 8.5, just the Versa outlet down which is what does the kalk dosing. Since then PH has been very very low. I didn’t Kalk dose last night. I just changed the media for a my recirc, and it’s moving up a bit. I assume the water is full of acids? When I woke up, water was almost as clear as it normally is, slightly hazed. All only jumped about 0.6, which hit the second shut down rule (>9 and it shuts down). Coral are all doing OK. Only a couple touch heads were grumpy. Should I just leave it be or do a decent water change?
