Another week gone by and its time to make sure the pool is properly balanced.
As usual it looks GREAT! I just re-balanced all the minerals after over filling the pool by about 50% and the water looks great.
Free Chlorine - .4 PPM
Total Chlorine - .4 PPM
More than enough. I also did a test for harmful bacteria that came back negative. The pool water is safe, even with the low level of chlorine. :)
PH - 7.8 to 8.0
I added 5 cups of acid to lower the PH. The PH can spike up to 8.0 for a while after adding minerals.
Total Alkalinity - 70 PPM
This is ok.
Calcium Hardness - 300 PPM
This is ok as well.
Combined with the PH, TA, CH, and temperature the saturation index is .14 - well within the proper range. Adding the acid will lower the PH and bring the SI back town to the .01 range.
Cyanuric Acid - 20 PPM
This is more than enough to maintain a .5 PPM chlorine residual.
Phosphates - 500 PPB
I need to do a concentrated phosphate treatment soon to nuke out the phosphates.
Borates - 80 PPM
This is perfect.
Our season is almost over. This has been another very successful and problem proof season. I hope you all enjoy your week!
