This was my first year with the pool and used TFP method all summer. With two weeks left till closing, decided that it was too much time and money to continue daily testing and bleach additions, so threw some pucks in a floater. I dont mind CYA rising cause only a couple more weeks.
The pool has been crystal clear with a reading of FC 8 with the pucks and residual chlorine that I added two days ago
My question is whether the TFP method really holds a huge advantage over pucks. I am not suggesting using pool store with all their products - that is crazy. But why not use a combination next year? The TFP testing and use of liquid shock along with pucks? This way won't have to worry about FC ever reaching 0 and might not need the daily addition of bleach.
In terms of price, I found that the bleach and liquid shock really adds up and the $100 or so for large bucket of pucks might not be much more expensive than daily addition of 1/2 to 1 bottle of bleach.
What am I missing?
