Brown Swimming Pool Water

Yikes! I have brown swimmingpool water. How do I make it blue?
Yellow and brown swimmingpool water is brought about by the chemical reaction of iron and granular chlorine. Since granular chlorine (calcium hypochlorite) is an oxidant, it reacts with iron to form rust when applied to untreated water which is added to treated swimming pool water.
This untreated water is often saturated with iron such as deep well water found in tropical countries like the Philippies.
So do not apply granular chlorine (calcium hypchlorite) on your newly refilled swimming pool if its water is still saturated with iron so as to avoid the production of rust, through oxidation, and, consequently, avoid brown or yellow swimmingpool water.
What should you do to solve this problem?
First filter your new swimmingpool water for at least 24 hours, and after you have removed the rust from your swimming pool water, you may apply granular chlorine on your swimming pool water. It would still be be wise, however, to hire a reliable swimming pool service company to solve this problem because if you do not solve this problem soon, your swimming pool tiles may be permanently stained by rust.
