## Questions & Answers

**Q: Is this considered a sequestrant?**
A: This product is considered a sequestering agent, yes. It prevents the formation of scale on your spa's shell and equipment.

**Q: What color is the solution supposed to be? My first bottle I bought was a light blue however the new bottle I got is almost a red rust color.**
A: Like an opaque brown. Previous packaging for this packaging had been partially see-through, so it may have been dyed blue for a better look before, but now the plastic  blocks all views so the color can be natural.

**Q: What are the actual ingredients in this product? Stain and Scale Control?**
A: The active ingredients are primarily acids. Including phosphoric acid, etidronic acid, and Butenedioic. These are at least the dangerous chems listed on the MSDS sheet.  The bottle simply reads "multiple active ingredients."
It's safe to use in your pool as directed, but don't drink it or get it in your eyes.  If it gets on your skin, minor irritation may occur if not washed off as soon as possible.

**Q: how often should this be used?**
A: I have used 2 oz a week in a 375 tub for over 20 years...last tub lasted 19 years

*by A***E on 13 April 2025*

I am giving it four stars, because of price. At $28+, the price is quite high. There are competing products here which are significantly less expensive for 32 fluid ounces, less than half. But I know it works, have used it now for two hot tubs. The problem with trying a competing product in order to save $10-12, the experiment could end in disaster for your water quality. More work for you, than 10 bucks could be worth. So I guess I just grin and bear it. I was priced around $22,, three years, ago. Like everything else, prices reach for the five stars, but I give only four....
