We recently moved across town, and I am putting in a pool as soon as my PB gets through the municipal and HOA permitting processes.
I previously installed an IG pool in North Houston in 2011. The PB I used at that time provided SWG/Nature2 System for my white plaster/pebble interior 13.5k gallon pool. Pool School instructed me to keep FC in the 0.5-1.0 ppm range.
After startup was complete, I only paid attention to 3 properties....FC (tended to keep it in the 1-3 ppm range since it was too easy to use up most of the FC when we had heavy bather load), pH (goal was ~7.4, but it took 1-2 quarts per week in the swimming season to maintain...a situation I am now attributing to frequent use of my water features), and CYA (target set point was 70). Other than adding acid once or twice a week and attenuating duty cycle on my SWG, I did no other routine chemistry maintenance.
From day one, I had the cleanest, clearest water imaginable, and it stayed that way for the 3 years I owned that home. Never was any funky colors or cloudiness observed, even though my water temperature would get up to low-to-mid 90s in July and August. However, after reading various TFP forums, I now know that the Nature2 can be more trouble than it's worth and my FC/CYA ratio was too low.
My new pool will also be SWG (no Nature2!!!), and I want to make sure the water looks as good as it did in my last pool. I'm planning on going with the TFPC (BBB) method as soon as soon as I reasonably can. Since this method should give me the results I want, I am not worried about having any issues.
However, solely as an academic question, I am really wondering how I was so successful with my last pool even though I didn't have the best operating plan. Was my monitoring and maintenance really adequate for my conditions, or was I just perfectly lucky for the last 3 years? Any thoughts?
