    Weird Blue and Gray Spots on the walls of the pool

    Thank you for everyone's green pool problem. I'm finally getting good readings on my chemistry. Now I have another problem, but was not sure whether I should start a new thread since it is a separate problem or continue on the old one. If I was suppose to continue on the old one, I apologize and could the Mod kindly merge this with "trying to restore green pool" thread.

    Well I see weird discoloration on the walls and the steps of my pool as you can see in 1.jpg attached. Is this something that can be corrected by treating the water or is it something what will have to be repainted?

    Second minor question is, what is that pipe sticking up from the middle of my cartridge filter in 2.jpg?

    Don't know about the spots, but the pipe in your filter looks like it's there to help the cartridge stay centered when you put the top back on.
    (This is my guess, since I have a sand filter with a pipe sticking up, for centering the valve assembly.)

    It's an air bleed tube with filter.

    "repainted"?
    Can you add your pool specs/equipment to your signature... go to User Control Panel, then Profile, then Edit Signature.

    yep




    First question the pic is hard to determine what you are asking. What kind of pool do you have? What was the original color of the pool, do the spots come off or does it looked like it is chipped off?

    Not sure what the original color was. I'm assuming blue? I tried scrubbing it with a brush, but it doesn't seem to be coming off. It is a concrete pool? there's no vinyl liner or anything.
