Well, I just called the manufacturer and have bad news. I asked if the product has stabilizer and was told that it does, in fact contain it. That was good, but I asked about the 41.8% of "other ingredients" and was told that there are clarifiers, filter aids, and buffers....all things that you do not recommend. Unless you tell me otherwise, I am going to return this and then use the stabilizer that I already purchased (product of china...ugh!!!)...along with doses of 6% bleach. How does that sound?
