Spectracide Stump remover says contains Potasium Nitrate and after review online, so does MSDS sheet. So, why is Greg Watsons pure white and this stuff is off white? Is it a different grade, or ??

Just want to make sure this is okay prior to exposing my fish/plants.

Thanks,

Ted

Not sure what fillers may be in there, but it should work the same. Greenlight stump remover has a color to it, too.

the off white is probably impurities. It's probably just ash.
