I've been lurking here for some time and finally took the advice to order my own test kit and take care of my own pool.
The funny thing is that there is a CC reading of 55, which repeated twice. Most folks post a reading of 0.5 or so. I'm not sure what this means, if it's good or bad, or what to do about it, if anything.
The instructions included with the kit were followed diligently both times. I did indeed put 110 drops of R-0871 in the second part of the test.
Other notes, recently did an AA treatment and have been adding bleach every day or so, two gallons at a time, to get the FC to hold. It just started holding over the weekend.
The pool water is crystal clear.
The pool was re plastered about 5 years ago.
Just added some MA to bring the pH down from 7.5 and then some HEDP sequesterant (HTH) because the return jets showed stains returning.
Iron staining is a constant battle in my pool due to rusty screws in the cage overhead.
Any help or advice would be greatly appreciated.
