yesterday evening's test results:
tested @ 10:15pm FC=34 CC=1.0

this morning tested@ 7:00am FC=33 CC=1.0

getting better…

i had a question about testing with diluted water: I am currently testing using 5:1 ratio (distilled/pool). Is this OK or would a smaller ratio ( i.e. 3:1) give me more accurate results?
