New pool owner and recent convert to the TFP method. Using the TF100 test, my CYA=100, so I know I need to drain water, but really don't want to do that until the season is over. So I am left with maintaining a pretty high FC between 7-12. My questions are: Because my FC level needs to be higher than 5, do I have to use the FAS/DPD daily? Is there a way to dilute the water and use less of the drops or use the OTO test for chlorine that is higher than 5. Thanks.
