What should my TA be for a non swg pool? The card that came with my test kit says between 100 and 120, and Pool School says 70-90. I had been following the card, since I see it every day but just noticed the difference while I was reviewing pool school following my third AA treatment (yes, when you let the pH drift to 7.5 the stains come back). Also, can you leave your pH between 7 and 7.2 indefinitely?? Lastly, I read on "Pool Forum" about filters you make with socks and quilt batting and attach to your returns to actually remove the metals from your water...does anyone know if this actually works?? I live in fear of needing to shock and starting the whole process all over again....
