dying tang from pH drop?

I posted this in another forum also

Tuesday night my pH dropped from 8.3 down to 7.25 within a few hours. My co2 tank, for some reason, started giving off a tremendous amount of gas- enough to push most of the water out of the reactor. I did not have my controller set right, so it did no good.

I obviously shut off the gas, added my old skimmer to my sump to aerate, and added some limewater to bring up the pH a bit. By morning, pH was back to normal. I have a mixed reef, and the only thing that showed any reaction at the time was the anemone, who deflated to half its size.

I came home tonight(2 nights after), and my blonde naso tang is nearly dead. It is lying in the corner, gills barely moving. My other fish are fine( a scopas tang, clown, blenny, and damsel).

Did the pH drop cause this? Is there any way of saving him now?

Thanks!

If it came form your CO2 tank, chances are that your tang is suffering from a lack of oxygen rather than the PH droping. Do a water change if you can.
