I can't answer your question, but I also would be more than concerned about putting that much acid in my pool. However, my pool is a liner pool, so some of the other folks with experience with your pool finish should be by shortly and hopefully can give you some useful information.

I do want to remind you, though, that you're going to need to do whatever has to be done in order for them to warranty your pool, if you're still within the time period--even if that advice differs from what you read here.
