I am a new pool owner as of July 2019 and I've been following the TFP method. It's been great! However, I tried an alternative method (as an experiment) to deal with a high CC level in my pool and the results were not what I expected. I was wondering if anyone has ever seen anything like this before.
I keep a daily log of my pool test readings. Here is what happened starting 3 days ago:
T-2:
FC: 4.4, CC: 1.0, pH: 7.2, CYA: 70 | I added 1lb of potassium monopersulfate (to oxidize the CC as an experiment) and added only 60oz of bleach (6% chlorine)
T-1:
FC: 7.2, CC: 0.6, pH: 7.0 | Added 1/2 Quart of Orenda SC-1000 Scale & Metal Control, Added 3oz Orenda CV-700 Enzyme Water Cleaner & Phosphate Remover, and added only 30oz of bleach.
Today:
FC: 0.0, CC: 0.1
The pool has been under very minimal bather load over these three days. I find it VERY interesting that the FC and CC readings today are basically both zero. My hypothesis is that that the combination of the KMPS and the CV-700 broke apart almost all of the combined chlorine and the chlorine demand in my pool skyrocketed in a very short period causing all of the FC to be used up overnight. One other thing to note is that the pool water has been very clear this entire time and there is no visible sign of algae.
