Been nervous at work all day not knowing what's going on with the tank. Not too concerned with the 4 part... it's the kalk in the ATO that's got my attention. 3 hours to go before I can check on things and test the pH for spikes... started biting my knuckles now that my fingernails are gone.
Getting some weird looks from the guys on my build team.
