Well here is the outcome, I think.
My local pool supply store told me I needed to add stabilizer to the water as my Cyanuric Acid was gone. I added one cup to the 9000 gal pool that read 300 plus. Now that the level is too high and the water has been in it for about 5 years, instead of waiting until November to replace the water because although I have pebble tec lining its extremely hot here in Arizona and I want to avoid any chance of damage to it. I am using a pony pump to drain it slowly each day allowing the make-up fresh water feed to add new water to see if the acid reading it comes down. Do you think this might work?
