HYDROGEN PEROXIDE Aquarium Treatment For Shrimp & Algae - H2O2 Uses in Your Fish Room 

I think you should have emphasised the use of PPE with peroxide. Even a tiny droplet can cause a nasty burn, and a miniscule airborne droplet landing in the eye is horrendous. I started using peroxide in 1972 to sterilise nets, gravel and to extract fossils, and I can testify to the results of these types of random events. Wearing latex or nitrile disposable gloves and a basic visor may sound somewhat OTT but these simple precautions can save you a visit to the ER and a week off work. BTW, if you are going to talk chemistry, the hydrogen peroxide molecule is composed of two ions of hydrogen and two ions of oxygen. The H2O2 molecule is unstable and readily releases its oxygen ions when it contacts organic matter, stripping electrons in the process. The liberated oxygen ions re-combine to form diatomic oxygen molecules and form the bubbles that can be seen. You can use H2O2 to disinfect fish eggs, but take care using it in tanks where fry are present.

Nice video, really helpful info. Thanks!

Great information Joseph

This is the best explanation of using hydrogen peroxide within the aquarium I’ve seen. Love that you used it on a smaller tank, love that you explained the risks and gave dosage info for gallons instead of litres, love that you showed us treating the whole tank as well as spot treatment! I will be subbing, thank you ❤

H2o2, always good to have a bottle or two in the house. 👍💕👍

Perfect for my needs. Well done. Take care.

YES! Always wanted to get rid of the mold in my python!!

Thank you, Aquarium Tom Hardy. Good video!

Good info. Tnks for sharing.

Awesome video Sir. By chance can you explain how to disinfect wild collected aquatics plants like lilies, ancharanis and hornwort to make fishsafe? Thank you for sharing.

Thank you for all of the info, especially for mentioning how to treat with peroxide in regards to snails. Any advice for treating algae that is growing on a snail's shell?

Use a Söchting Oxydator. It micro-doses H2O2 and mine lasts about 3 weeks in the tank before needing a refill.

Great video! Why don't I see any bubbles?

This is so helpful, i didn't think to add the substrate on, and didn't know about dosing! But I have a 5 gallon worth a home made sponge filter, in a water bottle with floss on top. The black hair algae is all over the top! Can I spot treat this or will it kill my filter? I have my red guppy female breeder in the, she's very old...

Thanks for the video! How long until it kills the algae? When can you add more? I'm using it for terrarium mold, but not sure how long it will take.

Thanks Tom

I learned that my Hornwort plant didn't like the H2O2 very much. It nearly killed it, but overall the tank is thriving with life. I have several other plants along with shrimp and fish. I used 2ml per gallon for my treatment.

How to keep clean and clear fish tank glass.. .. .

Will it hurt fish? I have some guppies in with the cherry shrimps

Does this work for vorticella?

Great stuff! I use 1.5 ml/gallon. I also use actual gallons of water volume not Aquarium size. Many folks forget to account for water levels, substrate and decorations. At those concentrations I have not experienced any deaths of any snails, shrimp or fish. If you have shrimp leave the material and they will enjoy eating it up. Most fish will eat the dead algae as well. Even those that would not normally have that reputation. The peroxide leaves no residue only water and oxygen so I rarely follow with water change. In fact normally I physically remove algae, then water change and then treatment. Thanks for the video!

you probably have enough plants in those little vases to just do top offs and no water changes right? Also, for the mosquito larvae you could probably put some least killis in those vases too lol

Hi, it's been awhile since you posted this so I hope you still have the channel and are answering questions. I think you mentioned turning off the filter so it wouldn't kill the bacteria, but you didn't mention how long to wait before turning the filter back on. Thanks

Damn Tom Hardy be teaching me about Hydrogen peroxide lol

I just run a little glass oxidizer ceramic base with catalyst pellets. You can leave it in the tank and it slowly pushes out bubbles that never harms bacteria or worries

Would you recommend periodic small doses directly into the water column? Sort of like a med coat just to keep bacteria in check somewhat?

Way cooler than Tom Hardy

Is hydrogen peroxide safe for turtles?

will it kill any parasites in aquarium?

Where is the sound?

That would be 75708.2ml for 20 gallons or 315.4508333 cups of h2o2. Source is online converter.

Just for the sake of information i've tested hidrogenperoxide on dwarf puffer fish and apparently they aren't sensible to it.

I followed this advice to the letter, measuring the peroxide exactly and it killed EVERY LAST SHRIMP AND SNAIL in the aquarium. Total wipe in a matter of hours. Also, the hornwort is shedding like crazy.

Be sure to turn off the lights for a couple hours or the day when using H2O2 (hydrogen peroxide). photo-degradation.

OK, here's the skinny on using hydrogen peroxide to kill algae in an aquarium. 3ml per gallon, 5ml per gallon or even 10-15 ml per gallon to be honest, isn't going to hurt ANYTHING if the procedure is done properly. Spot treating is almost always a pointless endeavor that's going to be a reoccurring merry-go-round that's never going to stop because 99% of the time when you notice a spot of algae whether or not it's regular green algae, staghorn algae or green hair algae, there's more than likely some algae hiding away somewhere else that you just haven't noticed yet or is just to small to see yet. So you think you just killed your problem algae only to have another spot of algae pop up somewhere else 6 days later. The easiest way to eradicate the problem once and for all is to treat the whole tank at once, wiping out any and all algae. Shut down your filtration and then start syphoning off your water as if you were doing a 75% water change. At that same time start dosing the peroxide equally through out different areas of you tank until you know for sure covered the entire tank. Here at Aquatic creations/Gardens, we use 15 ml pipettes to do the dosing throughout aquariums. In a typical 20 gal high aquarium, we usually end up dosing about ten 15ml pipettes of h2o2 equally spaced throughout the tank. Whaaaaaaaaat, that's a total of a 150ml or 7.5 ml per gallon of peroxide!!!! yep, sure is. The thing is, it LITERALLY only takes 20-30 seconds of contact between the peroxide and the algae for the irreversible killing damage of the algae to be done. And in that time you finish off draining the aquarium of 75% of the water without haste, and then immediately start refilling the aquarium back up again. By the time you do this, and get your tank filled back up, whatever remaining peroxide that is left in your tank is so diluted down that it totally harmless to ANYTHING, and then you can fire back up your filtration and then sit back and watch all the algae suffer and die over the next day or so. We've used this process hundreds and hundreds of times over the years on nano tanks, 20 gal, 75 gal, 125 gal, 250 gal, 400 gal etc etc, with zero ill effects on any of the aquariums or even small ponds inhabitants, accept of course, for the algae.

I have thousands of snails and they crawl all over the thing

lol He does look like Tom Hardy

You killed your fissidens with this?
