I just got my TF-100 and my results are:
What I need help with is that I can't keep FC levels around 3 for more than 3 or 4 days. I assumed my CYA was super off and was causing the FC to be "eaten", but this does not appear to be the case.
12,000 gallon above ground pool. I opened it about a month ago and have been checking the FC levels every 3 or 4 days. Is this normal since I'm only getting FC up to 3 and not something like 5?
