2 year old pool, San Francisco bay area, maintained by others up till now. I am the owner and planning to do it fully myself starting shortly but haven’t yet given notice to service guys. I've read quite a lot but am unencumbered by experience
The pool is currently clear and water quality appears fine. It is covered most of each weekday, only uncovered in late afternoon/evening. It is uncovered a lot more at the weekend but timings vary. It is 89 degrees without heating at present.
I’ve ordered TF Testkits but in the meantime took the water to a good reputation local pool shop for a testing baseline and found the following:
FC - 0.65
CYA - 5
CC - 0.12
Salt - 2679 (at odds with the control system which is reporting 3292 ppm average salt level)
PH - 8.1
TA - 93
CH - 254
I am assuming that things are working OK despite these FC levels because the pool is mainly covered and there isn’t much CYA.
However I believe the pool is vulnerable especially if we uncover it more or if pH naturally drifts any higher.
I am trying to work out what order to fix things. Current thought is to hold off on addressing low CYA for now and do the following:
Is this a good plan of first few steps or should I be doing something else?
Any other recommendations?
Thanks!

- Increase period of SWG function to increase FC (30% --> 50% of filter run time)
- Clean SWG cell to see if that brings salt reading more in line with pool company test - maybe recalibrate?
- Add Calcium Chloride to increase Calcium levels per TF calculator calculations
- Add Muriatic Acid to reduce pH per TF calculator calculations, which should further increase FC
Is this a good plan of first few steps or should I be doing something else?
Any other recommendations?
