I've been out of town all day, and out of cell service for a large part of that. So, when Angie came home to our 200 gallon tank, full of dying fish, she did the right thing, by starting water changes and doing water tests, until able to contact me. She also contacted Barbie at Aquarium Solutions for advice. Thank you Barbie!! Thanks are also due to Kevin at Aquatic Dreams, who gave me advice, later, on a chemistry question.
Anyway, as I was saying, Angie came home from work to find my oldest 2 daughters panicked and all of our fish dead or dying. Our pH was below 7.0 and she immediately started water changes. As soon as I finally got home, I immediately noticed that our Co2 tank was sweating. It was empty, and had emptied quickly. It seems the solenoid stuck and the entire Co2 tank dumped into the sump, plummeting the pH and raising the Alk to 28 dkh!!! No, unfortunately that is not a typo. I was only able to get an accurate test reading, after consulting with Kevin, since the test took 1 3/4 syringes of KH reagent.
So far, we've changed 50% of the water, moved ALL SPS and some LPS into our 40 gallon and moved what fish still seem to be breathing into the 40. I'm sure none of the fish will survive though. Some of our SPS has already experienced RTN and are completely white skeletons, from the major spike in Alk.
Our fish deaths so far are:
Female of our pair of Blue Jaw Triggers (male soon to follow)
Purple Tang
Scribbled Rabbit
Male and Female Benghai Cardinals
So far, I've been unable to find the Male of our mated pair of Black and White Occellaris.
The following fish are sitting on the bottom of the 40, still breathing, but I'm sure will be dead soon:
Female B&W Occellaris ?? Not sure if it's alive still or not
Male Blue Jaw Trigger
Starry Blenny
Lavender Tang
I believe that accounts for all of the fish that were in the tank.
We'll see if we wake up tomorrow to a 40 gallon tank full of white SPS skeletons.
