HOLY Deepend Batman! 80,000 Gallons!
Get into Pool-School NOW! read read read and get a handle on pool chemistry or that is absolutely without a doubt going to be the largest home pond anyone has ever unintentionally constructed. Not to mention the amount of $$ you will spend guessing and over reacting to things you don't understand.
Test your water yourself and stay ahead of it, it can be the best experience of your pool life, fail to take everyone's advice and I can't even imagine what a nightmare that will be.
Be concerned, be very concerned. The struggle will be what you make it.
Thankfully you have a very large support group, but just like all support groups, if you do not take the advice, you won't get much benefit out of attending.
Best of luck, everyone here is cheering your success!
