I have a couple of questions with respect to transitioning into a maintenance mode and setting chemical targets for my pool. First of all, this morning's test run produced the following numbers:
FC 2 ppm
CYA the test still does not obscure the black button at the bottom of the tube but the tube water is now visibly cloudy. I am about to finish adding the 1st four pounds of CYA that have ever been added to this pool (I was on Baquacil previously). A water test at a local pool store detected 6 ppm of CYA present.
The PH has risen this week (it was around 7.5) but we have had 5 days of rain here (probably totaling 3 or more inches).
I am continuing to add CYA via the sock method.
Each night, I am adding about 1/2 of a 121 oz bottle of DG or Fred's bleach (8.25%)
With respect to targets, I used this page and chose the vinyl with bleach section.
Unless someone suggests otherwise, these are the targets I will use in the pool calculator.
FC 3-7 (See chart)
CH 0-350 (Don't add)
- Should I adjust the PH now (while the CYA is still being added)?
- I am continuing to add CYA to arrive at the target zone. This process is taking several days - is that a concern?
- With respect to the ideal FC zone of 3-7, if I add bleach around sunset one day, ideally how long should I wait to measure the FC?
- Are there any areas of concern I am not seeing here?
Thanks to the experts around these parts, the pool currently looks like this:
