This is my second season with TFP. Last year we bought a house with a neglected pool. Being totally frustrated by the ineffective and very expensive pool store suggestions, and becoming disgusted by the chemical soup we were concocting in our pool, I desperately began searching for help after my husband threatened to call a cement truck to fill in the pool. He was serious. TFP helped me turn our thick, dark green, smelly frog swamp into sparkling clear water. Thank you!
Last year I was just content with no longer having a frog swamp, but was challenged by keeping up with the daily-ness of testing, brushing, and hauling bleach. (We traveled a lot and have an erratic schedule.) This year I plan to stay on top of it so that I do not have to shock again. Last year, it took a tremendous amount of work. This year, I want to enjoy our pool more.
Last month, about two weeks too warm, I pulled off the disintegrating cover and saw slightly cloudy, slightly greenish water. I scooped leaves, vacuumed to waste, brushed, and began a week-long shock process. I was unable to test and re-chlorinate as often as I should have, so it's taking longer than it might have, and it's not quite finished. I'll be at home tomorrow, so I'll be able to check levels more frequently. The water looks clear, though it sparkled more last year than it did today.
Here are my numbers from 10pm this evening:
Sorry for the long intro. Here are my questions:
Do the numbers look good?
We have full sun all day on the pool. What CYA level is best? There seems to be a significant difference between 30 and 50.
Poolcalculator suggests FC range of 4-8 with CYA at 50. How do I determine where within that range to keep FC level?
For that matter, how does one determine where to land within any of the ranges? I've skipped quite a few hours of sleep over the past week by reading the forum, but I haven't discovered the answer to this question, except pertaining to eye irritation for pH.
Maybe I need to just take a deep breath and not borrow trouble from tomorrow. But I see no need to reinvent the wheel or do unnecessary trial and error, when more knowledgeable people than I probably have the answers to my questions.
Thank you, knowledgeable people!
