What is the best way to look at your chemicals when testing (I use theTF-100 test kit)? Do you hold them toward the sky, put a white piece of paper behind them, look at them in the garage, outside by the pool....?
The colors seem to be slightly different dependent upon what the test is being held up to. Just wondering if there is a standard procedure that is recommended.
Thanks!
