Last week the pool wasn't circulating properly because of a very dirty filter. This week everything seems to be flowing just fine. We've had tons of rain so I was kind of nervous about the pool but once again my worrying proved pointless.
Pool looks magnificent;
Free Chlorine - .6 PPM
Total Chlorine - .6 PPM
This is well within the proper range for low chlorine chemistry.
PH - 7.4
This is exactly where we want PH for chlorine function and bather comfort.
Total Alkalinity - 60 PPM
My PH has held at 7.4 for many weeks now, I do not want to mess with the alkalinity content and risk losing this perfect buffer.
Calcium Hardness - 275 PPM
Last week with the water not circulating I only got a reading of 225 PPM. When water doesn't circulate properly concentrations of certain balances can change dramatically. 275 PPM has been the calcium reading for some time now.
Cyanuric Acid - 15 PPM
This is enough to help protect the low level of chlorine in the pool while also allowing it to be as active as possible.
Phosphates - 300 PPB
This is coming down as I continue to add CV-700. Once the rainy season is over I should be able to maintain a 0 PPB Phosphate level.
Borate - 80 PPM
Perfect.
I also added the monthly maintenance dose of Scale Tec. I have been using Scale Tec since December and have seen some improvement to the scale in the pool as well as a lowered calcium level. I would say it is working rather nicely.
Until next week folks!
