My roots are juat starting to dip down into dwc resevoir. I notice they are brown, slightly slimy. I have some hydroguard coming, but how much peroxide (weak 3 percent) will take care of the roots in a 5 gallon dwc.

Hey, I found the below info. Of course you will have to adjust accordingly. Hope this helps.

H2O2 comes in several different strengths: 3%, 5%, 8% and 35%, also sold as food grade Hydrogen Peroxide. The most economical is 35% which we recommend be diluted to three percent before using. When working with food grade H2O2, it is very important that you clean up any spills or splashes immediately, it will damage almost oxidize everything very quickly. Skin will be temporarily bleached pure white if not washed cleaned. Gloves are strongly recommended when working with any strong chemical.
Food grade H2O2 can be diluted to three percent by mixing it one part to eleven parts water (preferably distilled). The storage container should be opaque to prevent light from getting in and it must be able to hold some pressure. If three-liter pop bottles are available in your area they are ideal for mixing and storing H2O2. There are twelve quarter liters (250ml) in three liters, if you put in one quarter liter H2O2 and eleven quarter liters (250ml) water in the bottle it will full of three percent H2O2 and the bottle can hold the pressure that the H2O2 will generate.
Three percent Hydrogen Peroxide may be added at up to 3 ml's per liter (2 1\2 tsp. per gallon), but it is recommended that you start at a lower concentration and increase to full strength over a few weeks.
For hydroponic applications, use every reservoir change and replace twenty-five percent (one quarter) every day. Example: In a 100L (25gal) reservoir you would add three hundred ml's (3%) H2O2 when changing the nutrient. You would then add seventy-five ml's more every day.
