I've been using the TFP method for three years with no hiccups. This summer, I went on an unexpected 1 week trip when the temps in Dallas were over the 100 degree mark. When I returned, my FC levels were at zero. I started feeding the pool liquid Clorox, which it consumed at an alarming rate. All other markers were at pool school levels (CYA at 50) other than the chlorine and the water was crystal clear. I immediately went into slam mode and kept the FC levels over 25 ppm for two weeks. At that point, it was still consuming over 6 gallons of 6% bleach per day, so I drained the pool before leaving for a 10 day vacation.
As I drained the pool, I noticed that the surface was white rather than the Aqua Blue pebble sheen color we had purchased 3 years ago. When I returned from vacation, I cleaned the grids in the filter and started to fill the pool back up. I decided to remove some efflorescence around the hot tub and poured some acid on the build-up. When the acid ran down the wall, the streaks turned from white back to the Aqua Blue color we had three years ago. I'll attach a picture of that.
My question for the TFP/PebbleSheen gurus is ... Do I have a service chlorine/acid wash my pool before filling it, or do I fill it and then drop the PH down to a level where it will remove all the white residue from the surface? I'm not sure if the white surface is related to the crazy amount of chlorine I was dropping in, or if it is something that will go away with a low PH level.
Thanks!
