freshreef · 11-09-2004, 03:53 PM

Ive read all about it here and in the krib and would like to give it a try. could u guys tell me from your own experience what is the side effects and if it helped u remove the algae
1. how to dose and what is the recommended dosage that i should use in a planted tank with fish n shrimps?
2. does the hydrogen peroxide help with all the algae kinds? and if yes - should i use different dosage with different kind of algae?
3. first of all would like to try it in my 30L tank that has green water more then 3 days

About H2O2... I tried that in my tank, and it's only effective over the blue algae, cyano... no with nitrate-algae or another kinds...

About dosage and aplication... 5 or 10 ml each 100 liters, it's recomended... application, just over the cyano, without mercy

SORRY FOR MY BAD ENGLISH! :S

See ya!!!!!

had a MASSIVE ..and I mean MASSIVE staghorn infestation. 2 consecutive days of 2oz (1/4 cup) into my 30g. came home from my trip 4 days later and there wasn't a SINGLE SIGN of staghorn in the tank. ..not clogging the filters, or anywhere. Didn't loose a single fish, plant or shrimp that I could tell.

I have also heard that black beard algae (another species of red algae, along with staghorn) is also very sensitive to H2O2. Have not tried it myself.

I tried H2o2 on BBA. It looked up and laughed at me after bubbling for about 30 min.

H2O2 is good for a number of spot treatments I think, if you have lots of algae, best to remove it by hand first, then kill off the stragglers.

Full tank treatements might help tip a slight imbalance, but so would a tank cleaning. Add that to any treatment method BTW.
The problem with chemical treatments with a strong oxidizer are fish and plants can be fried if you do not do precise measurements and just dump what the person thinks is a fair amount, does many treatments every few hours etc.

You can get more effective use from dosing about 2/3 of the day into the light cycle also.

Turn off all filters etc for spot cleaning.

Some folks can use this and treat whole tanks with some success if they are careful.

Everytime someone post a H2O2 thing, someonme tries it and kills their entire tank of fish. It's not this gentle thing.
Same is true for copper but it's less lethal to your fish.

I personally don't use any anti algae chemicals since back in the 1990's nor need to nor really recommend them, but folks seem enamored with them and focus less on the plants. Algae killing is fun I suppose..........then it comes back, then you kill it again, then it comes back etc etc.

For spot cleaning, I just lop off the leaf or scrub it off. I use the plants and plain old mainteance methods to deal with algae.

Hey Gomer

Did you have to do any water changes after the h2o2 into the tank? Some ppl tell me to have a massive water change but you mentioned nothing about it, pls help clear up this matter (pardon the pun )

Cheers

I used 2ml H2O2 per US gallon on a 30g aquarium to eradicate thread algae. I dosed two days running, 60ml, midday without removing fish or turning off the filter. There were no casualties, except the thread algae which was completely gone at the beginning of the third day. Tonina sp., Anubias, Marsilea sp. all survived. The fish showed no stress.

I used H2O2 to spot treat BBA on another aquarium without much success. Spot treating is an art, perhaps, which requires a good sized long syringe. In the end removal of rocks which had BBA (without returning these rocks), cleaning of the filter tubing with H2O2, and washing the filter and media in dechlorinated water, and vacuuming the substrate carefully was the key to eradicating BBA - along with increasing the CO2 level and ensuring it was consistent (in this case changing from DIY CO2 source to pressurized supply).

Help me try and understand this please, you are dosing this ratio straight to your tank water? No spot treatment?

I have some brush algae (I think) growing on some slow growers such as Anubias barteri that I just cant get rid of. Would this work? I have been thinking of removing the plant for a bleach dip.

Any good (reputable) online articles on this treatment?
