    Not sure if this is the right place.....

    My IG gunite pool has gray marks in several place, the worst being in the spa. You can't feel anything if you touch them, but they are unsightly. I've attached a picture....any thoughts on what this is and how to get rid of would be appreciated.

    Wow. I'm not sure.....

    Someone will be along tho.

    I've seen it suggested to rub a crushed vitamin c tablet on the stain and if it fades, the stains are metal. Also with a chlorine puck, let it sit on the stain and if it fades, the stain is organic.

    Hopefully if there is another suggestion for you someone will chime in.....

    I have something similar happening in my pool, figure an acid wash during the winter is due.
    My pool is a 10,500 gallon (420 Sq Ft ) kidney shape. A hand made sheer decent waterfeature. STA-RITE HRPB30, Sand filter 30" 98 GPM,
    1 HP Maxi-Glas 2 pump, BBB Method, Taylor K-2005 test kit, 50 Watt 12V low-voltage pond light illuminates the pool at night for a nice soft glow.
    250 gallon stand-alone hot tub. Got it FREE!

    I have the same thing on my steps. After reading one of the posts about the vitamin C tab, I found some and rubbed on some places and just let the others dissolve. I was amazed at how the area that I just let it dissolve became brighter and no more streaks. So... I am going to do the ascorbic acid treatment I read on another thread (getting rid of pool stains). Hope that it gets better.

    Re: Not sure if this is the right place.....

    Thanks to all for your suggestions...I'm on my way next door to borrow a vit c tab. I also posted this in the Algae part of the forum just to make sure its not algae, but this sounds like a consensus here...I'll try the vit c and then the AA.

    Thanks again!
