    Stains

    Hi
    i opened a green pool this year. After SLAM was finally able to remove the algae and have a blue pool. Now m vinyl cover has stains which look like algae at the bottom. We use well water in our pool and is high in iron content. I don't know whether these are organic stains, stains from the iron in the water or stain from the one bottle of BANISH copper algaecide I put into the green pool ( that was before I discovered this forum). How do I get to the bottom of these stains and remove them?
    Thanks!

    Try holding a triclor puck against the stain for 5 minutes. If the stain is seriously removed then its almost certainly organic. If nothing try some crushed aspirin in a sock. If that works its iron.

    Good reference is Here: Pool School - Metals in the Water and Metal Stains

    If neither of those work Go here and figure out what you have Stain ID Kit - 4 oz - #JMSTAINID - Stuff for the Pool - Our Stuff - Product Catalog - Jack's Magic Products, Inc.

    I thought it was Vitamin C? Never knew that aspirin is doing the same thing.

    That's news to me, too.

    I recommend the Vitamin C first. If the stain lifts, it's metals. Then the trichlor puck for five minutes or so. If the stain is organic, it will fade. The trichlor is also acidic, so it will also lift metals, which is why the Vitamin C comes first. The trichlor may give a false positive for organics if it's done first.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Yes, to start with any Vit C tablet will be fine.

    Just your normal vitamin C pills. I use 1000mg for my pool however I am not sure that even matters. I keep getting little rust looking spots in my new pool and the vitamin C pills remove them in seconds, they do seem to come back though.
