Results of Ascorbic Acid Treatment for Stains

On second thought, probably don't need bucket test at this point since I know meta is in water. Wouldn't bucket test be more appropriate after I treat again with HEDP product?

From Marie's and JimK's experience may be something to the calcium comment from JacksMagic, even though hard to explain. Time to order more HEDP - any preferences between KemTek vs. Pink Stuff? KemTek on sale on Amazon, but PinkStuff worked for JimK. Where do you get calcium chloride? Is that the product Pool Stores sell as Calcium Hardness Increaser - if I decide to try to up CH to around 200. Thanks for any thoughts or comments.

Just for clarity, I've never tried the Pink Stuff. I use the Purple Stuff which is formulated for salt pools (whatever that means).

When I was adding calcium, I bought it at the local pool store. I pretty sure it was refered to as Calcium Hardness Increaser.

The Pink Stuff is 60% HEDP; the KemTek is only 20%.

Is there anything you can think of that would make the Purple Stuff better for salt pools, like Jack's Magic states, than the Pink Stuff? On the surface it seems like at triple the concentration the Pink Stuff is a better value.

It's possible that the "Purple Stuff" has some significant ingredient in it that's low enough in toxicity so that it doesn't have to be listed on the MSDS. The way the MSDS is written, strongly suggests that the "Purple Stuff" is nothing but a 20% solution of HEDP in water.

When using the HEDP ( Jacks Pink Stuff) after AA treatment, water gets cloudy - I assume because it binds the metal in the water - does this cloudiness indicate there is metal in the water? Or, would water become cloudy using HEDP if no metal present? Trying to make sure I get enough in it before adding back chlorine. Cloudiness begins to clear after a day or so on its own.
