I'm a new owner of a IG 20,000 older cement and fiberglas pool at a campground and I'm getting a little nervous about my ability to get the brown monster open by Memorial Day weekend. I've been at this about 6 days and the water is still pretty brown (unable to see bottom at 5'). It also looks like the entire pool is one large rust stain.
I have been reading the forum and it has a lot of great advice about how to handle the rust (absorbic acid treatment is my plan), the problem I have is that every time I backflush my sand filter, I have to keep adding bad water from the well. Someone had recommended using a sequence of 3 whole house filters (RV type) with specific iron removing cartridges. I spoke to our local Home Depot and they have filters that remove rust and sediment, but nothing for just iron. The guy told me that the filters they have do not remove clear water iron. He also said that in order to remove the clear water iron I will need a iron removal system that costs about $500 and uses potassium promagnate? Does anyone know where I can get the clear iron removal cartridges or will the Home Depot ones work?
Great forum. Thanks for your help. I have to go backwash my sand filter again.
