My ph is fine. I've had the other things tested & treated all summer. I dont have a good tester; I have to take my water in to pool store. Does anyone know how to treat the SCALE? I test my ph all the time and treat as necessary with ph increaser, murautic, and borax. (only needed to increase ph once this season) 7.2 is the norm. Wouldnt all the rest of the chemcials be in balance if it is finally clear? Im ready to close the pool and I guess at this point I will have to get a new liner.
