Since I added Ascorbic acid from the plastic cup around the walls of the pool, stains came off that were close to the walls at the begining, then water became cloudy and after that they came back.

Now (as it was before) the whole floor of the pool is covered with a layer of stain.

As you know I bought 5 lbs of Ascorbic Acid and 4 bottles of Sequestering Agent, I used 4lbs and all 4 bottles on day one when I started all that.

Yesterday I poured in 2 more bottles of Metal Out with the pump off. Direction was to have the pump off for 8 hours (for stain removal process). It didn't do anything to the stains.

I had about a pound of Ascorbic Acid left in the bag so I droped it in and as soon as Ascorbic Acid touched the floor of the pool stain started to disappear around those spots. So I know that it is deffinately a metal.

CYA went down for no reason, I already put in 6 lbs of CYA into the pool and now it is back at 20-30. Haven't shocked the pool yet since the time I started all of this.

Now I don't have Ascorbic Acid anymore, all 5 lbs are gone, stain still there, sequestering agent is gone LOL. And I am out of $130. Expensive treatment that didn't do much. Don't get mad guys it's not your fault. Thanks for helping me. I am out of ideas on how much more of this freaking acid do I have to add.
