Assuming the folllowing parameters:
Jack's Magic Purple Stuff maintained at 20 ppm (using sequestrant test kit twice per week)
Jack's Magic Magenta Stuff added at a rate of 5 oz once per week
If I tested for iron with the Taylor K-1716 Kit Iron Test Kit, which uses reagents R-0851 and R-0852, would a low pH of 7.3 and the use of sequestrants bind the iron, or keep it in solution, so that despite there still being some iron in the water show a reading of 0 (zero) ppm, or if iron is present will it still be able to show that.
My guess is that it will show zero ppm but I am not sure.
Any help would be appreciated.
