Alright I have a stealth hydro type dwc. Got some Satori (3 weeks old) goin.
About a week ago, I noticed some white slime on their roots, I think only the roots that were under water. Well I started a hydrogen peroxide run, following amounts I have seen on this board and others. It didn't help. I even picked off some slime covered root and put it in a bowl of peroxide, just to see if it was something that was immune to it. The shit bubbled and mostly disappeared after about 20 minutes. Just today I snipped off the visibly affected parts and added some more peroxide. I looked a few minutes ago, and happened to see on of my bubble disks had flipped over. 'Well', I think, 'perhaps it is under-aeration that is causing the growth.' As I grab it, I recoil my hand in surprise. The side with the bubbles coming out is covered in slime! Looking closer, there are chunks floating around the res as well. Now isn't hydrogen peroxide and oxygen supposed to kill this stuff? btw, I have my dwc triple-lined with duct tape, have some cardboard cutout's covering the netpots, and I am getting a thermometer tomorrow but am pretty sure that temps are staying more or less in the correct range (65-68 ). Also I have grown like this once before, the only difference being I am using GH nutes this time.

general hydro flora series and no add's.
I cleaned and refilled my rez with distilled water, bathed all the stones and hoses in peroxide, and added two more layers of tape all around the rez. I also pretreated the rez water with an entire bottle (16 oz.). When I got back today I did it again. The smell of earthy rot (rather unpleasant and not so bad at the same time) has diminished.

I had this before although not this bad at all, what i did was clean my rez with water and perioxide, and you need to change your water weekly , at least biweekly at that age... use R.O water and put a tablespoon or so of perioxide every change in your water, it will oxygenate and keep your rez from getting slimmie... Let me know how this works out.....

Yes, i add with the nutes, i add everything to its own gallon of RO water makeing sure to add nutes and bloom booster first and h2o2 last.... you will notice a little burn but a very little, then i just ph my water and with using RO water only my ph is ALWAYS excellent....
Try it, research it first if you are kind leary.. Good growing

well i didnt read the whole thread, but only input i have is that the sh nutes allways gave problems like u are talking about..
switch to advanced nutrients and you problems will be gone maybe.. also the nutes have a great ph balance..+1 for advanced nutes grow bloom and micro.. cant leave out the ph down its a great product peace |

I don't think that root rot is pH related, at least the way I think about it. It's a pathogen that grows in warmer water. Keep your res temps below 75F and you'll be fine.

Thanks for all the replies.
As I said, I added an entire 16 oz bottle of peroxide for the 10 and 11, and have been going back to the suggested levels. I also picked up my ec to .5 from .2 with the rez change...recovering from some middle strength nute burn. Doesn't seem to be any funky smells beyond the usual in a dwc, at least usual for my other grow in dro. But my roots are browned a little. I would say it was from the gh micro...but those two days of full bottles likely could have screwed em up. Either way there is new growth.
