In an earlier post I indicated that my first water test I did on my refilled pool from the pool store indicated I had .2 ppm of iron in the water. This seemed odd at the time since I filled with city water from the garden hose.
Recently I did my first slam and had to maintain a FC of 16. I have just completed the slam and have notice no staining at all. Should I assume that I will not require sequestrant , and that either there isn't enough iron in the water to require it, or that the PS test was wrong?
Any my advice as obviously don't want to use sequestrant.
