So Chem Geek proper steps would be muriatic acid 30 minutes bleach? If that is the case then I just messed up because I added bleach then muriatic acid...Should I add sequestrant or should I wait until tomorrow to add sequestrant? New to taking care of 17,500 gallon pool. I have 4 ppm iron content due to well water. I filled the pool a week ago and have been battling ever since. Water is a light green and I can see the bottom, but it is obvious that there is still a tremendous amount of iron in the water because every morning the filter is a rust color. I want to be floating in a clear pool by Mother's Day!
