High TA and 7.2 ph

[PoolDoc]

Pool store test results aren't trustworthy, but it really doesn't sound like you have any particular problems with your water, that won't resolve with proper chlorine levels. Read the Best Guess page (linked in my sig) for part of the info you need.

• Do NOT put any more stuff in your pool. If you've got unopened pool store chemicals, either take them back or list them, and let us tell you what to keep and what to return.
• Do NOT add any more baking soda -- your TA is already plenty high.
• Fill out the Pool Chart (abt 30 seconds) so we can figure doses and recommendations:

• See if your local Walmart has the HTH 6-way drops kit in stock; if so get one. Otherwise, get a cheap OTO (yellow drops) kit. While you're there, buy 3 boxes of 20 Mule Team borax & 8 gallons of PLAIN 6% bleach per 10K gallons of water in your pool. Then go by Lowes, Home Depot, or wherever, and get a gallon of muriatic acid.
• Read the muriatic acid dosing guide in my signature. Do NOT add acid now.
• Read the test kit info page, and order a K-2006, unless you already have a K-2005, in which case you can get a K-1515.
• Tell us what your water looks and smells like currently.
• If your water is green, add 4 gallons of PLAIN bleach per 10K gal of pool water, now; if it's just cloudy, add 2 gallons. (4 ppm chlorine is NOT OK -- you DID read the Best Guess page, didn't you? )
