Yesterday I needed more MA so I took a water sample to one of my pool supply stores for a test. Here are their results and my commentary:
FC 4 (probably too low)
TC 4 (CC=0 is correct)
pH 7.8 (probably correct)
TA 80 (too low)
CYA 90 (too high)
CH 340 (???)
Salt 3700 (probably accurate)
Phospates 500 ppb (who cares)
Here are my results this morning with the TF-100
FC 7
CC 0
ph 7.8
TA 130
CYA 70
CH 480 (???)
The best part of the story is that after testing the water the guy looks at me with a very sincere look and asks how my water looks. I said it's perfect--could not be better. He looked confused and asked if I was sure. I said of course I'm sure and asked him why he would think otherwise. He said my phosphates were so high that I probably have algae. I smiled and said I'm not concerned about algae at my present chlorine levels.
Again, don't trust the pool store test results.
