Using Hydrogen Peroxide on Tomato Plants in an aquaponic system, good or bad

Pure H2O2 rocket fuel, or massively diluted as an antiseptic? Can't think of a reason for either in AP!

Bad.Don't let it touch the system,it will kill all the bacteria.They use it to sterilise hydroponic systems.

To use on tomato plants? for what?

I recently saw where you can use it on tomatoes to stop the wilt which we have bad in my area. If it is going to kill all the good bugs in your system steer clear of it. If you pee in the tank when you are taking anti biotics it will take ages to get your system up and running again. If your tomatoes are in the ground maybe okay but not in AP.

If you are talking about as like a foliar spray it would probably be fine, just don't want a lot of it in your system water.

I use a 3% food grade version of it for seeds I don't trust & micro greens that are to be given away.But only half a teaspoon in a good few litre jug of water.

Maybe something weak like that might help.
