Adding soda water can bring down the pH in no time. It's carbonated water so it won't add anything you have to be worried about. Start off slow with it though. A teaspoon at a time until your pH is back within safe range.
Thank you to everyone with all your comments and offers to help. Im keeping my fingers crossed. Im just not sure at this point if they will recover or just die. Ph is normal and lights will be comming on shortly.

That's an interesting idea. However, when the CO2 combines with the OH, it is going to raise your alkalinity. If you are going to go this route, do it slowly b/c a rapid increase in alkalinity is not a good thing neither.
Tom, that must sux, sorry to hear about what had happened. I hope losses are minimal. I agree with everyone here, waterchange is the best way to correct the problem. Good luck.
update - red sea sailfin died, luckly I found him and was able to get him out before he really started decaying. The acros, some look fine, some are dead, and some are boderline. The undata and the montis look like nothing happened. Tommorow I will do another 30 gallon water change .
