Hi everyone, anyone knows if we can get Hydrogen Peroxide 35% in Singapore? Could only get 3% concentration in pharmacies. Was thinking that the 35% H2O2 would be more effective in some serious spot nuking of BBA, Hair algae ...and we could always dilute it if it is 'too much'.
i'm using the 3% conc from pharmacy and i have to say that it is already pretty strong. it has worked for me in eliminating unwanted algae 100% of the time. i would advise against using something so concentrated even if you can find it. did you try turning off the filter before spot nuking?
Those from pharmacy are strong and effective enough, use it straight from the bottle without diluting it to "spot nuke" BBA with a Syringe.
...I love rubies too ...

I believe you require license to purchase Hydrogen Peroxide with more than 20% concentration

Yes. I was looking that SCDF link too.thanks.
Hey, sorry, so we just go pharmacies like Guardian to buy is it? Which section will it be under?
it should be under the antiseptic/band-aid.
Check with the store assistant, they are quite hard to spot. Didn't manage to find it last time I was there until I ask for it.
yea it is difficult to spot unless you know how the bottle look like
Buy the 500 ml bottle, it is much cheaper in term of unit price. Don't buy 100 ml, it will cost you something like $3.50 whilst the 500 ml about $5 - $6, I can't remember the exact price.
It is in a brown coloured bottle. Look under chemical section area at Guardian. Yishun Northpoint Guardian is selling. This is 3% not 35%.

Hi,
Think this image for the 100ML bottle will suffice.
Note that may not stock the 500ml larger bottle in all outlets.

Agree, not all outlets have but if you want to get the 500 ml, Northpoint Guardian confirm got.
Thanks for the pic felix! I went to Guardian (Novena Sq) just now and they don't have even the 100ml bottle!
just a note, do remember to get the big bottle. i bought the 100ml bottle and its disappearing really fast even though i only spot dose a few ml during weekly water change. the big bottle is more worth it. and get a syringe to go with the dosing!
Hydrogen peroxide has a fairly short shelf life, and needs to be stored in a cool dark place. Don't get the 500ml bottle unless you think you're really going to use that much.
Approximate Shelf Life before it starts degrading is: 1 year in sealed unopened container.
Or 45 days after you first open the bottle.

Just went to Northpoint Guardian Pharmacy just now, saw a lady bought the last 500 ml bot. I too missed the chance.
Another place I've bought Hydrogen peroxide before is Mustafa centre, but their prices have gone up a lot over the years.
When i bought mine, there was only 3 bottles left.
Bought at toa payoh hub guardian outlet, and in a good place.

O.K., so much abt where and the qty of the HP. Let's us know what do you with it? As for me, I used it to neutralise the Potassium Permanganate (PP) in my angels tank.
I use them to kill (nuke) algae in the tank. Just carefully dispense the HP with a syringe directly on the algae growth. You will see it working as the algae starts to fizz. Since the byproducts of the 'nuking' is Oxygen and water, it is quite a safe alternative to using Excel to kill algae. Its quite addictive to me since i am always bugged with hair or BGA.
