I'm a newbie pool owner. This was my first summer and I guess I had some great beginners' luck because I had no problems all season...until now. One week before I'm scheduled to have the pool closed.
I noticed yesterday that all white fixtures below the water were turning brown; the steps, the return, and the bottom half of the skimmer. I took a water sample to my pool store and they informed me it is stained from iron (which makes sense because I've been topping the pool off quite frequently with well water, which I know is hard water).
So they gave me a bottle of "Iron Out", which I just added to the skimmer. Shortly after pouring it in, the return started spewing out brown water! The label on the bottle didn't mention this might happen, the pool store of course didn't mention this might happen, and I can't find anything anywhere on the internet as to whether this is normal.
Could someone help me out? Is this normal? And if not, what do I need to do now?
Thanks for any advice
