I received my TF-100 and all tests went well except for the CYA, which I had to run twice I believe due to my incorrect interpretation of the instructions. The instructions state to hold the view tube at waist level, so you can look down into the tube and add the pre-mixed solution slowly until the black dot is totally obscured. The first time I looked directly down into the tube from the top and of course the black dot was never obscured in the clear solution. Common sense then kicked me in the *** and I repeated the process but looked through the tube still at waist level but on an angle and came up with a result of 60.
Can someone please just let me know if I conducted the test correctly the second time? I know there is no such thing as a dumb question but this just seems so simple I was almost embarrassed to ask.
Thanks for all the help and encouragement. I already suffer from OCD (as diagnosed by my wife and kids) and now with the addition of the new pool, I am starting to agree with them!
