Hydrogen peroxide newbie

kpunk said:

Hi there, i just obtained 50% hydrogen peroxide andvwanted to get some advice from ppl who have used it b4.

Im running a pipe nft system & have noticed a strange smell from the reservoir, also there's globules of brown stuff clinging to the roots...the roots are healthy & white for now.. so i wanted to do a quick flush with peroxide just to be safe & sterilize everything b4 i put a new feed in.

My reservoir is 300L .. Can someone give me a recommendation on dosage please?

I also have some of this arriving soon , i have never heard of it before but thought I'd give it a go -

Cleanse

Description Athena Cleanse is made from Hypochlorous acid. This mild acid is derived from salt and a proprietary electrochemical treatment process. The result is a unique, plant-safe chemical with powerful oxidative properties to prevent mineral buildup, increase Oxidation-Reduction Potential...

Also im going to try this Bacillus subtillis dry powder (same as hydroguard but cheaper)

Anyone that has any helpful information it's highly appreciated.

Thanks.

Be careful with the h2o2 at that % it won't take much.

If you're running hydro, go sterile.

H2o2 is good, but at 50%, it's extremely dangerous for your eyes and skin. Use PPE and store it properly, if you spill it, dilute with water before attempting to clean.

I have read about a 0.3% final strength solution is enough? ( im not planning on leaving it in the tank with other nutrients, only a quick flush & reload ) so about 600ml in 100litres of water. Need to make sure i get this right!

Thanks.

IS that the amount you would add to a reservoir of nutrients? That seems like alot for 50%. Don't do anything until someone explains exactly how the calculations work.

H2o2 keeps a hydro system pretty nice. Don't ever mix in silica with it..lol. You'll see..lol. Oops!

At 50% I'd use 1ml/4ltrs that's based on growth technology H202 recommendation of 1ml/ltr with 12% daily or 2ml ltr occasionally.

I wouldn't give a quick flush it's beneficial to have it in there its a source of oxygen and it'll fight nasties for a few days.

Fwiw 50% H202 is dangerous stuff exercise caution with it.

I did it once. Made a mess in my bubbler tub. Then I googled it. The two don't mix well. Some info said it could lock out a plant. All I know is it was t cool. Caused a lot of work.

Hypochlorous acid is great, too bad you paid athena 100x what's it's worth. Do a quick search on Amazon you can buy a gal for less than 30bucks. I have it in a thread here somewhere. It's what I use.

I found this for 13$ a litre. (hypochlorus acid ) What are the main differences / benefits of this vs H202? So far I've been told i can't use silica with h202.

Thanks for any info
