I have a pool store with a "WaterLink" testing center a mile from my home so it's pretty convenient. I bought this house last year on an "as-is" sale and I am trying to learn the craft of pool maintenance. The pool was horrible, but has been drained and pressure washed. I replaced all the equipment except the booster pump for the Polaris and the heater for the spa. Booster works fine and the heater wasn't high enough on our "to do" list this year. Anyway, every time I have the water tested, the pool store crosses out all the recommendations at the bottom and just says to add shock. So far, this week, they have told me to add a total of 18 lbs of shock, but looking at the levels and the pool school documents, I need to be doing more. Levels are listed below and I am going to switch to using regular bleach instead of the granular 1lbs packs at the pool store.
FC - 3ppm
TC - 3ppm
CC - 0ppm
pH - 7.1
CH - 150ppm
Alkalinity w/stabilizer correction - 50ppm
CYA - 1ppm
Copper - 0.09ppm
TDS - 500ppm
I have used the calculator on here and have the amounts of product to add that it recommended. Question is, follow the pool calc or the pool store recommendation?
