I received my TF-100 Kit today. It came with some Aqua Check Salt Strips. How accurate have others found these to be?
Here are the numbers from my first test session with the TF:
Is it normal to have such a high FC? My cell is generating at about 40% for four hours a day (12,000 gallon pool/spa). I need to add a little more acid to get get the PH down. Will this also lower the TA?
