Help with Stains in Vinyl Lined Inground PLEASE

[btozzo]

Hi All!

Of course I was joking, not even venting, about my boys. I wish I could freeze them at this age forever . . . Alot of fun, and in the case of pools, alot of work!

Anyway, I have no idea about how the stains got there. I don;t even remember if they were there when we moved in three years ago or not. I'll try the Vitamin C tablet, and bringing my chlorine up to 15 ppm for a couple of days. But I have a stupid question, when you say "Tablet" do you mean an actual little pill of Vitamin C? If it works, it would be a little like scrubbing the floor of a palace with a toothbrush. I found some threads in which some people use Ascorbic Acid powder from Trader Joes, but I could fins anything about how to apply it. Remember, the entire walls of my pool are stained. So should I just be adding it to the water? How much? I have a 25000 gallon inground vinyl.

Thanks everyone!

Bill

The vitamin C tablet is just a stain identification test. Hold the tablet on a stained area. If the stain will respond to ascorbic (or citric or oxalic) acid then the stain will disappear where you hold the tablet in about 30 seconds or so. If there is no change then ascorbic acid will not work (which means the stain is not metallic in nature).

Gotcha! Now, if I find that the Vitamin C tablet works, how do I apply it to the entire walls?

If it works, then you can buy some powdered vitamin C to use to do the ascorbic acid treatment. Read the sticky at the top of this forum called stain removal via ascorbic acid treatment.
