That is kind of a strange makeup.
I think You would want to flush it quick a time or two, or maybe run it down the sink.
That stuff may kill roots also. Guess that may be what the acid is about.
I used Rid-X for many years, when it came in liquid I stopped using it.
If you Flush some yeast, it gets the brew cooking, and is safe. But it does make some CO2 gas.
Have Fun.
