I have orange/brown staining in my pool which is pretty extensive. I did the vit C test which took the stain out. I am now treating my pool with the recommended product after getting the chemistry of the pool to the recommended levels. Now what? How long till I see an improvement? Hours, a day, 2 days or more? The instructions were pretty vague. I did this once before but it didn't work. I don't think I had all the levels correct that time though.
