today i woke up to brown water again. Called HTH and they said i must not of added enough Metal Control for it to take care of all the iron in my water. I did add what they told me. They said that I should take my water to pool store and get it tested, then they can tell me how much to add. Does anyone know if this is the correct advice b/c i'm about finished with my pool. I have been trying to swim in it since memorial day and haven't been able to get it clear. Please help.
