Need help with root rot

In short my friends resavor bublers got pluged and werent airaiting for a day or two, then one by one 3 died day after day for 3 days. Hes using 5 gal bucket ebb&flow, theirs still 13 left. We hit them with h202 and hydrezem, and 2 more died the next day. The rest look awsome and producing flowers, i was told regardless of how healthy they look they should be scraped and start over. My roots r slightly brown but dont really smell, They said once it hits a system theirs no way to rescue them is this true? Thanks ahead for any help and input.

Go get some Dutch Master Zone and follow directions, they should be fine.

how much h202 did you use. i hear making h202 half of your reservoir total liquid can cure most any root problems. an easier way would be to make bleach 5% of the total liquid.

You need 50% grade or 35%. 100:1 and 80:1 every 3-4 days or this will happen. Ditch the brown ones,theyre fucked, also drain and clean the res every 2 weeks with h2o2 at about 10:1.

are you sure you didnt get a little carried away with the h202? i did this once thinking i was helping, and killed them with it instead. dump the hygrozyme bro, that aint gonna help you with this(been there done that) most importantly what are ur res temps? no point in trying to fix the outcome, if you haven't fixed the problem.

what the btl recomended, 3ml per gl.using h202 29% oxidizer

The temps had me a lil worried especialy with the lil heat wave we just had.

Lower the res temps and stick with the H2O2 it might help but you won't get rid of the rot
