My chlorine is super high and I only have the Walmart 6-way test kit where the chlorine only goes up to a "5". So I was going to try the dilution method to see what my true chlorine was. However, the more water I add, the more ORANGE the water turns. Not yellow. I was going to use like 3 vials of the water and 5 drops of the OTO solution. Then mix and pour back into the vial and multiply the readout by 3. However, the more water I add, the oranger in color it gets. Anyone have an explanation for this? Am I not doing this right? Thanks much!
