Most pool stores do NOT provide a 'real' test. 'Real' tests are done with liquids, using either droppers or glass lab burets. Most likely they use 'guess-strips' just like yours, but read them electronically. This takes test results that are 'terribly inaccurate', and improves them to the point of only being 'badly inaccurate'!

There are a few stores around the country that still do 'real' testing: if you are fortunate to be hooked up with one of those, I take it all back.

I switched from shock to bleach this week and probably will start the full BBB method once I'm more familiar with it.
A *fundamental* component of the BBB method is periodic accurate testing, with reliable testing in between. Strips are neither accurate nor reliable.

You'd be MUCH better off tossing the strips, and using a cheap OTO/phenol red drops kit for daily testing, and getting a K2006 for periodic testing.
