For the last few seasons, I've seen more and more evidence of pool bottom and wall scaling. The pool is 10 years old (24K gallon), and the water comes from a well (which is hard to begin with). It's getting so bad, that swimmers come out of the pool with their feet bleeding. Very rough indeed.
This year, I want to try the No Drain Acid Wash for the next 5-7 days. Here are my current water conditions:
Temp = 74
FC = 3
CC = 0
pH = 7.5
TA = 140
CH = 600 !!
CYA = 0 (automatic pool cover, very little sunlight exposure)
I plan to take the pH down to 6.0, and brush 4 times a day with nylon and steel brush. I do not have a heater, no metals in the plumbing - so I plan to keep the pump on the entire time. That way, I want to see the cloudiness dissipate and perform necessary backwashing while the process is going on. If I can keep the water fairly clear during this process - the advantage is to know when the scale is gone, and then bring the pH back up using baking soda.
Is there a way to measure pH below 6.8?
Am i missing anything? This forum has helped me out many times in the past, and I'm getting a lot of education from other pool owners at TFP.
