Hey, I have lost about an equal amount of crop to harvest ratio due to root rot. So I know an awful lot about it now, let me try and help a bit.

First- The zyme products Canna/Hygro/Sensi are equivalent and people love all three, so use what you want. What they do is help break down dead roots so they can be reconsumed by the plant as food instead of rotting.
A zyme is not a bacteria, so it IS compatible with H2O2. Since your rez temps are ideal, then i believe that you can totally benefit from a beneficial bacteria.
Since you are going to go with a beneficial, you should stop the h2o2 it WILL kill the culture. (BTW you didn't say what percent h2o2 you were using). Now, your beneficial will need something culture on. So take a mesh bag or sock or something and stuff it with some lava rocks (NOT hydroton) and put your subculture onto that and put it in the rez. Also, as noted give as much air bubbles as you can, at your temp DO can be really high so take advantage!

Finally for now, decrease your PPMs and give it a double dosage of B-1. You may just make it, some plants will last out to harvest, but don't feel bad if you don't; generally they don't make it or make it worth it.
