Hello, I' trying to figure this out on my own but still not quite sure where to start after all the reading. I was fooling myself thinking that the chemistry must be correct since the water is crystal clear. Then I found TFP and purchased a Taylor k-2006. Please see my pool characteristics in my sig.. I don't want to do anything until I've confirmed with the experts here.
My readings today: Note: we've had LOTS of rain over the past couple of weeks and the water is a good inch high (I had to plug my drain due to problems)
pH - below scale - I'm thinking ~6.9
TA - ~50ppm (added 5 drops r-0009 before desired level reached)
Calcium - seems OK. Albeit at the high mark of 400
cya - below the indicator (seems to be around 130-140)
FC was off the charts. I'm sure this is not accurate since the chem is off.
If my understanding is correct I need to get cya in balance and then work from there?
