So, I have finally been able to enjoy our pool on a more regular basis now that temps are at 100 and above. Since we just finished our pool last September, I have yet to experience a full desert summer with the pool, so I'm sure there are many things I am yet to learn and discover. Right now, I do have a concern about high CH.
My latest results (K-2006 FAS-DPD) are:
CC - 0
FC - 3.0
pH - 7.5
TA - 70
CYA - 50
CH - 650
I have been able to keep everything in check except the CH. Right after the pool was first filled last year, it climbed to about 500 before the temps dropped off in fall. Now, as I am approaching 700, is this a major concern for the plaster and equipment?
Testing my fill source water (25 ml) directly out of the tap with the R-0011L it turns purple and with one drop of R-0012, it goes to blue, so less than 10, or zero if you don't count the drop after it changes. When I test the pool water, it starts out pink in color, changes over to purple around 400-450 and then to blue at 650. I have also run the extended test on this as well.
I assume I am getting so much raising of the CH from the large amount of water evaporation from the constant sun and triple digit heat and that the fill water is raising it. Or does the plaster have a lot to do with it as well still being so new? I do use trichlor tablets also and am not sure if they are adding to the issue either.
We actually just had the pool drained back in March as they needed to repair the mosaic on the top step so this seems to have climbed pretty quickly. Am I looking at having to drain my pool every 2-3 months just to keep the CH down? It seems like quite a waste if money on water and chemicals to get things balanced each time.
Any thoughts or help is much appreciated!
