Hi All,
I am having trouble understanding my CSI. In general I do understand what CSI represents but am having trouble with it and how it relates to my pool.
My pool is less than a year old and spent the end of the Summer and Fall getting things dialed in.
On 9/30/08 my numbers were:
CL - 10
Ph - 7.6
TA - 110
CH - 380
CYA - 45
Salt - 3500
Temp - 76
CSI - .01
Over the Winter my numbers have been creeping toward what I thought would be better and are now:
CL - 0 (this will be the subject of a different post)
Ph - 8.0
TA - 80
CH - 240
CYA - 80
Salt - 3750
Temp - 48
CSI - (-.33)
My biggest question is about the Ph. My normal target Ph when we were swimming was 7.5-7.6 and it occasionally would get as high as 7.7-7.8 before I had a chance to add acid. It has now settled at 7.9-8.0 and has been that was for quite some time. I know this is outside the suggested range but if I lower it to 7.6 my CSI will jump to -.7 which is too low. Should I lower the Ph and then raise the CH or just keep thing how they are until it starts to warm up?
Thanks,
Kevin
