Alkalinity Low??

Not sure if I need to do anything. I don't have one of those fancy test kits so I test with a drop kit. My TA is 60 and my PH is holding steady at 7.6. and has been for 4 days now. Water is extremely crystal clear. I was going to try and bring up the TA to at least 80 so I started adding Borax at a rate of 4 pounds over 4 days with this making no difference in my readings. I'm reading now that Borax isn't what I should have been adding. What did adding the Borax actually do to my overall chemistry?(If anything)
Should I just let the pool go for now as it looks the best it ever has in 12 years?
The pool is an IG 20x40 vinyl liner and 9 foot deep end. Thanks for the help!!

Borax raises your ph. Have you checked that lately to see if your addition had any affect on it? Baking soda is what is used to raise alk.
