Attached are my test results. I want to learn as much as possible to maintain my pool using the TFP method. I would like to know what you think I need to do?
Following is what I think. Please let me know your thoughts?
1) Free Chlorine is low at just 0.1ppm. So this tells me I need chlorine. The question is should I use the the powder chlorine (Calcium Hypochloride) or should I use liquid (Sodium Hypochoride) How much do I need to bring the range to 1-4ppm. My pool is 28,000 gallons.
2) Hardness is almost at lower range. at 175ppm. Do I need to fix this? If I do then how?
3) Cyanuric Acid is low. It is at 19ppm. I need to be above 30ppm. What chemical should I use? How much?
4) In what order do I need to fix each of the above?
Edit: I added 4 Gallons of liquid chlorine (12%) just 2 days back. Not sure why would my FC still be at 0.1ppm
