DWC Root rot prevention?

[TRED]

Hello you lovely bunch recently started my first DWC standalone grow using canna aqua. I have noticed single strands of root that has turned brown so I have been adding H2O2 daily but I believe that there are far more effective ways via adding good bacteria instead of killing good and bad with the hydrogen peroxide. What are people's thoughts?

Should I use cannazym and stick with the canna range or do I go for something like hydroguard

Reservoir contains aqua a and b, calmag, rhizotonic and h2o2 for the time being.
Res temp 20 degrees Celsius and a mistake I made was not filling the net pots to the top with hydroton and light was getting into the resivouir.
Any advise is appreciated thankyou

Hey @TRED brother. Firstly fill the rest of the net pot if you havent already.
You can add good bacteria by brewing teas etc. But its much simpler to use a product like sm90 or hydroguard.
Cannazym will not do the job on its own- dont quote me but i think its used to help break up any dead roots and turn them into food

I have filled the rest to block out the light, thanks will look into sm90 and hydroguard a bit more
