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.i have found a product down here called klaren max is is a algicide ,metal sequetstrent.i have water coming in from the city tap today(we only get it twice a week)so i usually fill the pool to almost overflow,then add a clarifier .i let everything settle out and waste out the debris in the morning.right now there is virtually no chlorine in the pool and it was pretty clear.i scraped down the walls so now it is a little cloudy.i was planning on filling it high today and adding the clarifier and vacumn to waste tommorrow.should i add the metal sequesterent then after the waste ,and when should i try putting some chlorine back in?i plan on backwashing and adding some diatomaceuos earth to my sand filter before i put in the seguestrent.i will add the sequestrent with the filter on recirculate then switch it back to filter after a while.thanks for any help
