Results of Ascorbic Acid Treatment for Stains

[JimK]

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.
