From your word "harp" in your first post I have sensed your resistance to the precise testing we teach. That's OK. Not everyone buys in to it.
However it IS what we teach because it works universally and the results are always the same....A crystal clear pool and an understanding of why it is clear and what to do about it if it gets unclear.
Virtually Every other method comes up short compared to TFPC.
