see previous post "does adding CYA cause cloudiness" from earlier today
the response I got "could it be calcium?" got me thinking - the landscapers were working in my yard today about 15-20 feet from my pool, sawing on concrete retaining wall blocks and dumping gravel. There was a lot of dust in the air. so I retested using TF-100:
Tc 6.0
Fc 5.5
cc .5 or less (1 drop)
TA 130
CYA did not test, just added today
CH 340/350 (tested twice) CH is higher than what I got a few days ago, but I'm not extremely confident in my results. I have the "fading endpoint" problem on my CH test, and I accidentally broke my magnetic stirrer. I did the 2 techniques described for "fading endpoint" to get my numbers, but even doing that I did not see a sudden change from pink to blue but rather pink--purple--blue taking about 5 or 6 drops.
I will get a new magnetic stirrer, but in the meantime, what should I do?
I will stop the landscapers for now, and look back at pool school about calcium.
I'm very concerned about scaling since I was already thinking I might have a litlle from earlier this summer when the pool was not as well controlled as I have had it in the last week.
any suggestions would be helpful.
