i shoudl still pump out all reamaining iron outwater once i'm finished and fill from scratch? No way to save it if it's only a small amount vs the 35K fill?

Has anyone determined how to use CuLator when filing a pool for first time? Do i put in sequestering agent to keep new iron away from freshly cleaned walls and add CuLator to autofill/hose area to absorb what comes out of the well then move to skimmer?

Looks like i may have some copper stains also. What is best for removing those?

Thanks agian
