Welcome to TFP!

Based off of these numbers, you need to do is bring your PH down. Anywhere between 7.2 and 7.8. Any higher or lower could create a lot of problems for the pool and equipment. Next, bring your CYA up to about 30ppm to start off with. Your TA is a little low and needs to come up.

Pool stores have been known to be off on there testing so your current numbers may be off. Order a good test kit of your own. TFtestkits or the Taylor 2006 kit are the best out there. See the test kit link in my signature.

Pool store testing is awful!! That said, they are usually decent at pH so you need to get your pH down into the mid 7's today using muriatic acid. Do that, post the results and we'll help you get everything else right.

Is this a newly filled pool? If so, can you tell us what chemicals you have added so far? I am wondering about the reading for Optimizer, have you added that or is that a bogus number?

Time to go to Home Depot and get Muriatic Acid! Use poolcalculator.com to estimate the right amount. That said, get your own test kit and your accuracy will go way up!
