I've a 27k gal pool w/ swg. It was maintained by pb for first 2 mo. the chemo levels seemed to be ok. I used the tf100 test kit. Now that the pb is no longer maintaining the pool, I measured Fc for the first time since the salt was added & got the following results:
Following the pool calc I added a gal of 10% bleach & about 20oz of cya to start... I tested FC the next day & still got a reading of 0.5... added another gal & tested again at end of day. It still reads 0.5... I thought maybe my reagent went bad so I diluted some chlorine in water & tested that. It read off the charts high...
Any idea why my pool FC is not moving at all?
