    Unknown Stains

    I gave some stains forming on my fiberglass pool,and have tried the vitamin C tablet test. The stains did not lesson and cannot be removed unless you take steel wool to them which I do not want to do on clear coat.the stains are brownish in color. I am in a rural area and all water is well water, even the fire department who fills pools around here. Stains are only on flat surfaces like seats and steps. Attached is picture...should I go ahead and to the AA treatment to see what happens?image.jpg

    Big question: were they high-quality Vitamin C tablets? That's not what you want. The pill coating interferes. The cheap stuff is what you want. If you have good ones, crush a few and try them.

    That may be the problem then...I will go by Wally World tomorrow and get some cheap ones. Nice thing is the pools is now crystal clear thanks to the DE sand treatment we did for two weeks! Bad thing is you can see these little stains now

    All I could find was vitamin C with Rose hips added...should I look elsewhere?

    Why not just crush up some of the ones you have already, to bypass the coating? If you don;t have any, just look for the store brand at Walgreens or RiteAid or wherever.

    Ok I got some cheap ones and tried rubbing on the stains, holding on the stains, and crushing up and using on the stains. None of these removed the stains...now what?

    Latest update! I crushed up about twenty pills into small chunks and placed them over a spot in the pool with several stains. I left them for thirty minutes and they dissolved into a fine powder over the stains. I then brushed off the powder and notice the stains are much lighter. With this in kind should I double the recommended dosage of ascorbic acid?
