I've been looking around for sources of concentrated H2O2, and have found a source that anonymously (via mail order) sells 50% peroxide for
hydroponics (it's called "oxyplus". They charge $20 for 500mL (), or $90 for 5L. Obviously the latter is better value for money. (someone tell me
if I am getting majorly ripped here, keep in mind its in australian dollars).
I would gladly buy the 5L, however, I'm thinking about decomposition. It would take me quite a while to go through 5L of 50% H2O2, and I'm
worrying about it decomposing. Does anyone know roughly how long it would last (natrually it's temperature dependent, so I might store it in a
fridge)?Twospoons - 25-4-2005 at 23:36
$90
You do know that Bacquacil "Shock" is 30% H2O2? I got 5l of that for NZ$28 at my local chemist. Its the shock treatment for the Bacquacil
pool treatment system.
The lid had a porous membrane in the top so I guess the stuff must decompose at sufficient speed for container pressurization to be a problem.

Fridge yes. Freezer no.

Just keep your peroxide away from radiation sources (sun, bright lights), extreme heat, and such; the stuff should then last you about a year and a
half, or more.

Thanks for the help guys.
Twospoons, I have found before a 35% peroxide mix, called 'spa shock' or similar, but peroxide was not the only ingredient in the mix. I
will ring around however and see what I can get. Thanks.
EDIT: I did a google search on baquacil and found this from The Australian Pesticides and Veterinary Medicines Authority (APVMA) website: http://www.apvma.gov.au/qa/pool_list_April_2004.shtml
(Information at the bottom of the page). It's called "baquashock", and the website states two other products with H2O2 as the active
constituent.

I found mine at Health Food stores. Its used in washing vegetables, and as a cleansing agent. 30-35% and it can be had in a various assortment of
sizes. tom haggen - 26-4-2005 at 16:17
I got mine at the local hydro store for 20$ a gallon @ 35%. Thats 3 liters and some change for you non-americans.

Wow, my local hydro store sells 500 mL of 35% H2O2 for $15 (Canadian). Sheesh.
. They charge $20 for 500mL (
), or $90 for 5L. Obviously the latter is better value for money. (someone tell me
