Noticed some flakes of white stuff along with the normal trash in my PoolSkim sock, they are not salt (I carefully tasted - no real taste). So, not only does the PoolSkim do a great job skimming, maybe it is also and early warning device! So, I check my chemistry:
FC: 3
pH: 7.8
T/A: 85
CYA: 60
CH: 500 (!)
Salt: 4500
Temp: 85F
Last time I checked CH was late April, and it was 400 (and 250 several months before that). So it has been climbing since the pool was completed in Sept. 2010. I add a little acid every week or two to keep the pH down. But now I am concerned that CH is going to get too high, and that maybe the white stuff is calcium that has precipitated out of the water. The water is clear now, but maybe not for long. I am not sure what is causing it to go up--maybe the make-up water? We have had very hot (100+F) and dry weather for months, and I have to add about an inch of city water every 5-7 days to cover evaporative loss. Our city water Calcium constituent is 14 mg/L, TA: 74mg/L, Total Solids: 174mg/L.
Do I have a problem, and if so, what should I do?
The salt reading, by the way, is too high (my target is about 3400) because I added a bag during the winter since the chlorinator was indicating low salt--then I read in this forum about how the salt readings are false in cold water! Oh well, I am slowly working down the salt by using pool water for other things (power washing, etc) and replacing with city water.
