Big TFP fan - the system is so easy and effective it turned the pool chores into NBD.
But I have a problem right now....
Average PPM chlorine consumption is running at 5ppm/day this year!
Previous years it averaged 1.2 ppm/day.
Already checked for visible algae, did OCLT, cleaned filter cartridges.
OCLT: 0.5 ppm overnight
Algae: nothing visible
Right now using the TF Test Kit:
FC 2.0 ppm (just measured and haven't put in today's contribution)
CC 0.0 ppm
(Using "Megashock" 12.5% sodium hypochlorite for chlorine.)
Any help appreciated....
