I woke up this morning and heard my kamoer dosing continuously running and discovered it had added over 750 ml of alk. I quickly ripped out as much sps as I could and placed them in my frag tank. I know they were exposed to the alk spike for less than 6 hours, but I’m guessing the alk is at least 40 dKh and could be as high 60 dKh. My Hanna checker is flashing 20. I had to make a delivery for work and am back home about to do a massive water change as soon as the new water temp comes down a bit.
