Been learning a ton here the last 2 months (thank you all!)
New home owner. Pool looked sparkling, pretty clear the day we first looked at it.
Read a paper report from July the cya was only 50. Hooray!
Not so fast!
Former owner had used the pucks (of course) I took them out after moving in 1 month ago.
Managed to get PH to 7.2 which was nothing when I first tested with TF100 kit.
Got the TA to a fair level.
But oh boy is the CYA off the charts. I even did the 50/50 dillution test.
I still can't get the beaker filled to 100 before it becomes impossible to see
through (have it on a magnetic stirrer with back lighting)
So I was thinking of a 45% drain next spring, but heard about reverse osmosis.
Is it worth it? I can't seem to find any places locally searching google.
any advice appreciated.
all hail tfp!
