physan 20 in my reservoir

So in an attempt to deal with root rot and other parasites/pathogens i added 10 ml of physan 20 to my 10 gal cloner reservoir. It foams up real nasty, and all signs of the competitor mold are gone. only now, my roots are staining redding and they seem weaker. My question is, is physan 20 only supposed to be used as a treatment with which you soak cuttings for a few minutes, and then replace them in normal nutrient solution? Should I not have added it directly into my res? thanks

Not really sure but I think you should check out HYDRO-FUNGICIDE 500ml [INS070] - $12.94 : Hydroponics, Hydroponics - Horticulture - Gardening

only supposed to be used for foliar spray!! i just found that out the hard way. not supposed to touch the roots. i put some in my aeroponics rez. and it is foaming like crazy plants are doing way worse than before i used it. the people at my local hydro store told me to not use in reservoir.

a more plant safe way would of been H202 I would drain that res asap and flush asap
