Is hydrogen peroxide an option?

Is hydrogen peroxide an option to a tank that is full of plants and livestocks?
Anyone has any experience in doing so? How much should I use each time? For how long?

Here's a good start

I have been using 10ml per gallon in my 60g to kill BGA. It has been working well. However, on two occasions, I killed some of my ottos when I exceeded that amount.

so...we don't add hydrogen peroxide directly into the tank? How exactly do we do it? I don't quite get it...I look really stupid...

you can use a medicine syringe and squirt it directly on the algae with the filters off, let it bubble away for 20 min. then restart your filters.

I'll just give this forewarning as someone who has used h202 in the past as a solution to algae:

Use it as a last-ditch effort.

H202 is the equivalent of fire-bombing an area to remove hostile enemies. It works, but does a lot of accessorial damage to the surrounding area.

I added it to my tank once. I used just a small amount and it killed the algae. It also killed my crypts.

The only problem I had is when I dosed more then 10mg per gallon. I did a 50 percent water change. Then not thinking I added it at the normal dose rate when I only had 50 percent of the water in the tank - STUPID!

Other then that, I have not experienced anything detrimental.

Haven't had any problems with it - using a syringe to directly apply the HP onto the ornament or plant with the algae. All the fish - shrimps, otos, dojos and such - didn't seem affected in the slightest. Have five red crypts in there as well and they didn't get affected either.

But, I will use Noahma's great suggestion to turn off the filters for a bit. Thanks!

I don't see how it will harm the live stock.... H202 provides O2, I use it when the power goes out and nothing is harmed.... I have been using 2-3 times a day for the past week to kill off some bba myself..... Dose 10ml per 10 gallons and turn the lights off for 1-1.5 hr..... I don't bother turning the filter off, I never did understand that one bit..... Regardless if it's on off it's in the tank.... It might be in there longer but the algae will also be in there.... I think I am at the end of my cycle with the bba, clearing up and now time to do a water change.....

Hydrogen peroxide breaks down into oxygen and water in water after 12 hours it's completely broken down. So you'll need to redose after 12 hours. Just don't go crazy, I've used it for algae and fin rot at 7-8 drops per gallon (just estimated)

I actually picked up that trick (the whole method) from a post Tom Barr made several years ago here

I would offer that it would be worth a few min. to read the link I posted. I'd refer you specifically to the posts by Dark Cobra. There are some misconceptions post on this thread that he does a good job of explaining.

It's an oxidizer like bleach. Too much would have the same effect as bleach.

I used a dropper and squirted 20 ml over my moss and fissidens to kill some cyno. It killed the cyno no problem but the moss and fissidens also took a beating...
