Sodium pyrophosphate in 3% H2O2 as stabilizer reef safe?

[Muffin87]

I can't find food grade anything where I live because food-grade isn't a thing here.
I found a good source of hydrogen peroxide 3% that contains sodium pyrophosphate.

I'd imagine the sodium pyrophosphate acts as a stabilizer, and should be present at about 25 – 250 mg/L.
Is this amount of sodium pyrophosphate gonna be reef safe?

I'd dose hydrogen peroxide 3%:

• at 0.9 to 1.59 ppm directly in my reef (in case of a fish parasite outbreak).
• at 150 ppm as a 30 min fish bath!

Thanks!

Tagging along here. In the US, some H2O2 is stabilized with tin (colloidal stannates). I want to avoid using that. I can get 7% H2O2 that is food grade.

I doubt the pyrophosphate addition is any concern. I would be more concerned with tin for something dosed regularly, but it still may not be enough to be problematic.
