Hydrogen peroxide 35%

[KWL]

downside is they do seem do damage plant tissues also, and my japonica pretty damaged now.

H2O2 is a bleach, so it is expected

Don't use the 35% in your tank without diluting it first! 3% is strong enough for spot application to kill hair algae. I have used 6% for the same purpose and it killed some of my moss, so 35% directly would cause severe problems!

Also 18% is too stronge, believe me! I had a bottle of 18% upstairs that exploded when the weather warmed up. Lucky it was in a foam box and only the cap broke off. 35% would probably be explosive even at 25C or below!

Price wise, if you plan to dilute the stuff you might not really save much money either, so just get the cheap 3% at the Pharmacy.

lol... normally after H2O2 we do WC.

I think even after my nuking's WC. My heart still say "Got some left"

Should have seen this thread earlier, i tear down my tank due to BBA. Really piss, the blackout method don't work, change water 50% also don't work. What i did last was to throw everything out!!!

Do i need to remove my shrimp when i nuke them? Any Adverse effect?

[felix_fx2]

hi bro, you might wish to play safe.Heard from other bro its like bleach.
Cause all my snails seem to dislike the environment after i nuked the place.

Now my japonica looks VERY Ugly (Period) for 2 weeks already.

Remember to spot nuke with pumps and filters off. My snails and shrimps doing fine with the still water so that the h2o2 don't leech all over the place.
Recently got my hands on some 15% and tried nuking. It proof to be too strong for some plants and my some of the HC melted as a result while other plants seems ok.
To help you see where the h2o2 is after you squirt them, you can also add some food coloring to it.

mjck, does your snail avoid zones where you did spot treatment?
They seem to move away (Most climbed up the tank walls) until my 2nd water change after spot nuking. Perhaps my WC after spot nuking was not enough?

Snails are more sensitive than shrimp in my experience with peroxide treatments.
Usally I have a few ramshorns that die after treating. oO

I don't do any water change directly after treatments normally, unless there is some serious green hair algae buildup which would foul the water if it were to die....
Keep in mind the H2O2 is not applied directly into the filter media or substrate (that might cause some of your benificial bacteria to die off, fouling the water).

Felix, my snails (ramshorn) didn't behave that way. I usually pick them away before spot nuke. My tank is cube-like with ~120L volume, dosed 20ml without any adverse effects. Infact I didn't do wc sometimes after nuking when I am lazy . You should try adding food colors to let you see where the h2o2 is going.

Hi guys can h202 be stored in a plastic container? I'm thinking of buying the 500ml, and recycling them for use to soak my glass lily pipe periodically.

[tetrakid]

What do you mean by recycling them?

Peroxide is just like sodium hypochlorite bleach (household bleach), but more expensive and strong. It is a also a strong bleach itself. So treating it as a bleach won't be far wrong. Using it for disinfecting pipes and accessories is fine, but good rinsing afterwards is important.

It needs to be kept in dark bottles. Plastic should be fine, and like said by others, it's shelf life is short. Exposing it to light shortens its life fast.

For treating the whole tank, all livestock should be removed. It will also kill all the beneficial bacteria instantly upon contact.

Thanks for the reply.

Would the 3% H2O2 be enough for preparing rocks from the floor for aquarium usage? Or must higher concentrations be used..
Man that would mean a LOT of H2O2. Poor wallet,

[Zeonic]

You can boil the rocks using water instead.

[jemswira]

Well I'm going to do a cichlid hardscape so It would involve way too much water boiling etc.
Also i read from somewhere that its dangerous to boil rocks.

[Zeonic]

Oh I see. How about using diluted bleach?

[tetrakid]

Household bleach is a good disinfectant, but it sticks to the objects (eg rocks) after the treatment and is difficult to rinse off. Boiling may work, but then might as well do with boiling alone.

Peroxide is another good method, but if concentration is too strong, it will discolour the rocks by its strong bleaching action, apart from the greater cost.
