New Pool Owner, Starting BBB method & Other Test Kit

Very few poolwater chemistry problems warrant a FIX IT NOW but unreadble low pH does.

What he said . . . so, add a box of borax daily, till your pH exceeds 6.8 WHILE you are working on the other bits (getting kit, learning, etc).

I yield to Big Dave's knowledge on hard-sided pools. Get your pH back up! But vinyl pools are even more sensitive to low pH and too high FC levels (not a worry for you).
