H202 will kill all the Micro organisms in your coco, so its not really recommend in coco unless u have severe root problems

It actually breaks down to H2O...the extra O2 atom is unstable so it jumps "ship" a quickly as it can oxidize something such as bacteria, mold, rot, ect. ect. This oxygen atom is extremely reactive and will attach itself to either another O- atom forming a stable Oxygen molecule or attack a nearby organic molecule. Both the stable and O- forms will increase the level of dissolved oxygen (providing the roots with more oxygen). Pre treating the water supply with H2O2 will drive out the Chlorine many cities use to sterilize it. This will also degrade any pesticides or herbicides that might be present as well as any other organic matter. Well water can be high in methane and organic sulfates, both of which H2O2 will remove. Many disease causing organisms and spores are killed by Oxygen, the free Oxygen H2O2 releases is extremely effective at this. H2O2 will help eliminate existing infections and will help prevent future ones. It is also useful for suppressing algae growth. The free Oxygen atom will destroy dead organic material (i.e, leaves roots) in the system preventing them from rotting and spreading diseases.
Roots require Oxygen to breathe and low levels are the main cause of almost all root diseases. Both soil and hydroponic plants often fall prey to the same syndrome although it is rarely recognized as what it really is. Hydroponic crops often fail due to "root rot" and soil crops succumb to "over watering." The real cause of both these problems is a shortage of Oxygen at the root zone. In a soil system the soil consists of particles, a film of water on the particles and air spaces between the particles. When too much water is put into the soil the air spaces fill with liquid. The roots will quickly use up what Oxygen is dissolved in the water, if they haven't drunk enough of the liquid to allow air back in to the soil spaces they will stop working. In this situation roots will start dying within twenty-four hours. As the roots die the plants ability to drink water and nutrients will decrease, this will cause symptoms of nutrient deficiencies (mostly pale, slow, weak growth), and strangely they will start to wilt like they don't have enough water. It is easy to make a fatal mistake at this point and add more water.
In a Hydroponic system the cause is a more direct simple lack of oxygen in the solution; this may be from inadequate circulation and/or aeration. High reservoir temperatures also interfere with Oxygen's ability to dissolve in the water. Temperatures above 70F (20C) will eventually cause problems, 62F-65F (16C-18C) is recommended( the use of peroxide also enables temps in the resevior to go a little bit higher then recommended without causing alge, ect.). The same symptoms will appear as with soil plants but you can also check the roots. Healthy roots should be mostly white with maybe a slight yellowish tan tinge. If they are a brownish color with dead tips or they easily pull away there is at least the beginning of a serious problem. An organic, ‘dirt like’ rotting smell means there is already a very good chance it is too late. As roots die and rot they eat Oxygen out of the water, as Oxygen levels are even further depleted more roots die, a viscous circle may be well under way. Reduced Oxygen levels and high temperatures both encourage anaerobic bacteria and fungi. The plants may still be saved but you will have to work fast.
When plants are watered with H2O2 it will break down and release Oxygen into the area around the roots. This helps stop the Oxygen from being depleted in the water filled air spaces until air can get back into them. High Oxygen levels at the roots will encourage rapid healthy root growth. In a Hydroponic system H2O2 will disperse through out the system and raise Oxygen levels as it breaks down. Strong white healthy roots with lots of fuzzy new growth will be visible. This fuzzy growth has massive surface area allowing for rapid absorption of the huge amounts of water and nutrients needed for rapid top growth. A healthy plant starts with a healthy root system.
H2O2 comes in several different strengths 3%, 5%, 8% and 35%, 35% is also sold as food grade Hydrogen Peroxide. The most economical is 35% which is recommend be diluted to 3% before using, as at this high concentration it can cause damage to skin and clothing. When working with food grade H2O2 it is very important that you clean up any spills or splashes immediately, it will damage almost anything very quickly. This is extra important with skin and clothing. 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. Three-liter soda bottles are ideal for mixing and storing H2O2. There are twelve quarter liters (250ml) in three liters, if you put in one quarter liter (250ml) H2O2 and eleven quarter liters (250ml) water in the bottle it will be 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 three 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. Use every watering even on fresh cuttings. For hydroponics use every reservoir change and replace twenty-five percent (one quarter) every day. Example: In a 100L reservoir you would add three hundred ml's (3%) H2O2when changing the nutrient. You would then add seventy-five ml's more every day.
35% food grade: called food grade because it has no toxic impurities. Of course your local hydroponics retailer, whom you can locate over the web.(there may be shipping restrictions on high strength peroxides). The local feed supplier may have it in small towns. Prices range from fifteen dollars per quarter liter to eighty dollars a gallon. One gallon will treat up to fifty thousand liters of water.
3%5%, 8% Can be found at most drugstores or pharmacies, prices start at a less than a dollar for a one hundred-ml bottle that will treat one hundred liters.

The bagged stuff usually has added micro orgys.
Unless you are trying to grow organic, don't worry about killing them.
You shouldn't need h2o2 unless something is wrong, though.

^if u use anything organic I wouldn't use it, also dunno if u use it but h202 will kill mycorrhizae

It will definitely help keep it clean.
Their standard nutes are chem, the Bio line is organic, so you are fine.

Thanks!
The filters are replacement pre filters for a mag drive pump.
I got mine locally for about $5, but here is a web link:

No need for bennies in a chem grow...
Hello all,
I use 3% H2O2 in my organic soil grow every watering/feeding at 20cc/l and have excellent results...my overwatering issues have vanished and hte root growth in much better then when I was not using it.
Now this is just my situation so take it for what its worth.

it's going to be ok with the nutes-there is nothing in them that it will disagree with-but-as some of the guys have said it's not recommended with the coir. Canna advise against it's use with their coco-but you know how these things go-it might turn out to be fine. Would be interesting to know how it worked out if you try it
cheers

There is absolutely no reason to use H2O2 in a coco grow. The beneficial organisms will keep the bad ones in check as well as provide benefits. There is also no reason to recirculate. If you are using H2O2 and recirculating why in the world would you choose coco as a medium? Growrocks will provide better aeration.

the Lion is going Guerrilla...
I've used a lot of H2O2 to offset fungus gnats and I've never had a problem at all. Daily multiple feedings and 2-3 tsps a gallon and it never gave me any shit. I don't depend on a microherd though and I much rather be the one in control of the rootzone, so yeah... They say you can come across fungus if you reuse coco that has the beneficial organisms killed off but what's that matter if you're using H2O2? I wouldn't use it with any form of organic nutes though.
BlindDate - Probably because it's a lot easier to keep a plant alive in coco with failed pumps, hot ass res's, blah blah blah, than it is pure hydro...

Can anybody confirm that bit about H2O2 helping get rid of Chlorine ?
My friend has some problems that are down to the [different] water and Chlorine is suspected to be the cause, he does drip to waste in Coco mainly because of the poor water quality - it just seems to be the simplest system as well as the most forgiving hydro medium.
