I believe you wil get a 'reaction' when combined if consintrations(sp) are to high. Fumes would b caustic. Good Luck

What are you trying to do???

Mixing and Acidic solution with an Alkaline solution to a neutral pH will give you water and a type of salt depending on the substances used. H2O2 is just water with an extra O molecule which gives it it bleaching properties. Are you talking about mixing H2O2 & and household bleach? I don't think this will give you water and a salt. Pure Hydrogen Peroxide has a pH of 6.2 and household bleach contains NaOH amongst other things. NaOH (Sodium Hydroxide) has a pH of 13 so it'll take a hell of a lot of H2O2 to get it to pH 7.

Are you just trying to give the roots a clean??if so i'd just stick with Hydrogen Peroxide (H2O2 as it breaks down into water fairly quickly and the pH is perfect for out beloved plant.

Bleach contains sodium hypochlorite not sodium hydroxide.

Household bleach is (regular bleach), in general, a solution containing 4-6% sodium hypochlorite and only 0.01-0.05% sodium hydroxide. This small amount of sodium hydroxide has only a very small effect on the pH of the solution once it is added to the diluted nutrient solution.

Use one or the other not both bleach and hydrogen peroxide. Bleach has a residual effect for 24 to 48 hours when dosed properly. Hydrogen peroxide does not have a residual effect meaning the treatment with hydrogen peroxide is not as effective as bleach over a period of time. It is also very hard to detect levels of hydrogen peroxide after it is added where it is easy to obtain testing equipment to read the amount of both chlorine total and chlorine residual. Bleach is also much cheaper to use and hydrogen peroxide in high concentrations is often hard to purchase. It is much aesier to make mistakes usinh hudrogen peroxide then when using bleach. Hydrogen peroxide is a stronger oxidant then sodium hypochlorite (bleach).

Your dead right sorry for the bad info.. However sodium hypochlorite still has a high pH of 11.

I tried dwc for 3 months and finally gave up the other day. Drove me nuts. Kept getting light brown slime and roots would fall apart. I usually use coco which is very easy.

Bleach had no effect. I think I had cyanobacteria. If you ever succeed, let me know what you did. I'm all set with brewing up teas.

Hey no disrespect to hydro growers, I actually love hydro,but its more of a love/ hate relationship cuz she broke my heart so many times. I thought she was the one but I dunno. she killed my babies many times and she had bugs, sometimes she was a little schizo, and was even cruelly over fed at times making her angry. ya shes a bitch but I still love her, I wish we could get back together one day and make more beautiful trees together.i swear ill treat her better and wont make her eat gauno and fish poop anymore.

salt <> NaCl but NaCl = a salt

You consider calcium hypochlorite instead of bleach? There's lots of discussion in this forum on the need for calcium and the desire to avoid sodium. It can be found as the only ingredient in certain brands of pool shock.

Unless of course you have a source for reasonably priced 35% H2O2.

Yeah the problem with H2O2 these days is if you want it in large amounts people think you want to take down am airliner. I brought 25% from a pharmacist in central london on questions asked.. After the tube bombings you just couldn't get it anywhere. Really is great for cleaning out the soil of my old bonsai mothers.

What about hair styling places... or rather... where ever they get their supplies from? They use it for bleaching peoples hair... just a plausible excuse for you.

H202 is commonly used to kill algae in pools and spas.
Check the active ingredient on the label. The ones you want clearly list hydrogen peroxide. Different brands have concentrations usually between 25% & 35%. About $20/gallon.

Carboy,
Got a linky? I've never seen it in the pool section of a store.

I'll try to remember to look to see the last brand I got.

EDIT: Aqua Silk Chlorine-Free Shock Oxidizer
Have never had it shipped but here's a place you can get 4 gal for 60 bucks w/ free shipping. That oughta last anyone for awhile!
http://stores.mkmpoolspa.com/-strse-5010/Aqua-Silk-Chlorine-dsh-Free-Shock/Detail.bok?category=

I really haven't seen a pool/spa supply place that didn't have it.
Again, the important deal is to read the label. It'll clearly say hydrogen peroxide. The inactive ingredient is water. Percentages vary.
Hope that helps.
