I have just taken over maintaining the water from my builder and was wondering why following the suggest values in pool school shows "potentially corrosive" on the pool calculator. Water values using the TF100:
FC 4
PH 7.5
TA 90
CH 280
CYA 100 [builder said he recommends 100...]
Salt 3100
Borate ~15
Temp 70
CSI -.48
Is CSI not an issue as long as the other values are in range? I also noticed its fairly easy to go into the corrosive range when at the minimums of the ranges.
Also, since the builder put the CYA at 100, I was planning on letting it fall over time. Is leaving it at 100 going to be a significant issue?
The TA just jumped in the last few days. I will probably drop the PH closer to 7.2 as was suggested for the first month while the pebble is still curing. I'm not sure how necessary that is given the CSI.
Any advise would be appreciated. This website is very helpful... only wish I had found it sooner.
