i have a problem with alot of iron in the water.i`m in southern mexico and many people have had the same problem this year.for some reson there is alot of iron in the city and my well water.when i add chlorine to the pool it turns green.i can put in a clarifier but then have to vacumn out to waste the debris and then need to add more water,vicious cycle.if i add a metal sequestrant does it settle out the iron to the bottom of the pool like a clarifier?
