Root Rot Help

I have come to a conclusion that my plant is suffering from root rot. The first symptoms were yellowing of the lower leaves and then when i when to change my res the roots stunk ! The smell is like rotten eggs really not pleasent, from this ive come to the conclusion i have root rot. So i took action and bleeched my roots and bleeched the res but it seems to be coming back. Im in the second week of flowering now and want to get this sorted as soon as possible does anyone have any recomendation about how to get rid of this and how to prevent it from coming back ?
Any help apreciated, Thanks Frankie.

Hygrozyme get some! Then and make it part of your hydro regiment . Some will say H202 and if you want you could use that to kick start the healing but its an every 3 day maintenance issue.

It went anaerobic for some reason (no oxygen)... try not to let that happen again in the future. Hydrogen peroxide can kill all sorts of stuff as it reacts and produces oxygen, so in your situation it would be helpful for those two reasons (at least until you could get something else). I don't do hydro but I would suspect proper aeration is important.
