I am an 15x48 Intex Pool owner in Upstate New York and new to the forum! I have had one heck of an awful season trying to keep my water clear! I spent most of June getting it clear and then I get it clear and then just this past weekend, literally overnight...my water turned brown and I mean brown!!! I took my water in for a sample - they tested it - told me all my levels are high - sold me PH balancer, Pool First Aid and Black Algecide - I've added all and my pool is a clearer brown, but still brown - it looks like my pool liner is stained - all the connectors have this brown residue on it, the cartridge is crazy brown (I've been rinsining every day) and my hoses have turned brown too - has this happened to anyone else who owns an Intex pool - It sounds crazy - but it almost seems like someone vandalized my pool and dumped brown food coloring in it! Oh and btw...today all my levels were really low - they told me not to add chlorine and shock until it is clear - I AM SO STRESSED OUT! I would welcome any help at all!!!
