I moved to a new house with an inground pool. Its been an expensive learning process. When the pool was first opened there were brown stains on the steps and bottom of the pool. I used Phoenix Super Erase and the stains were gone. I was adding the maintenance dose of Super Erase but the stains came back last week, especially on the stairs. Used more Super Erase and backwashed and backwashed. The stains are slowly coming back. The water was tested for copper and iron but there wasn't any according to the pool store. My pool store has been really helpful; the first one wasn't.
Here are my numbers from my TF Test Kit:
When the directions say keep adding drops until the water turns either red or blue, should it be a true red/blue? When I did the test the water looked more pink than red, and the blue was a pale color. Trying to get the color a real red I added over 30 drops and it still looked pink. The numbers above were from the re-test I did, not the 30+ drops.
I have an inline chlorinator with the 3" pucks. Can anyone offer some insight on what's going on? Thanks,
