Slime mold in hydro - how much H202 to add?

I have a slime mold problem in my DWC set up. My girls roots are covered in the stuff. Apparently 3% H202 can help with or actually solve the problem, but i don't know exactly how much to use. Can anyone help? Also, what about dipping the roots in H202, or maybe a diluted H202 solution? Any suggestions greatly appreciated!!

No one can tell me?

1 tsp per gal, I dont go above 2 ever. You could also check out hydrozyme it is good for breaking down dead roots that have been suffocated by the mold.

Sounds goo, I'll try it. Thanks for your input.
