With an AG pool, i wouldn't worry about the TA if your pH is pretty stable. Your pH is great at 7.4. So, you really don't need baking soda nor Borax at this time.

How do you know you have algae? You report a CC reading of 0. Not always, but usually when you have algae you'll have a CC reading.

With a CYA of 88, you need to be keeping your chlorine level between 5-10 all the time and your shock level when needed is 20ppm.

Test your chlorine tonight when the sun is off the pool and then again in the morning within 2 hours of sunrise. (Test FC and CC both times.) Report back how much FC you lost overnight and what your CC reading is. Then, we can help you determine what your next steps are.

How does the water look?
