No, it comes diluted, typically 17%. 5ml/Litre of that would eliminate any infection, pathogen or vectors for them.
These are a greater threat in DWC because warm water is very hospitable to them.
In any event, it will still increase oxygen availability to the roots.
It’s a good idea to run a low dose such as 2ml/litre routinely in DWC. It keeps the setup clean and better oxygenated.
H2O2 is water with an extra, unbound oxygen molecule. It is in effect, liquid oxygen.
Plants take CO2 from the air via the leaves and oxygen at the roots.
The oxygen molecule in water is bound so roots in DWC can’t get it.
This is why oxygenation is vital in DWC.
