The problem with mains water is that the councils are more and more using chloramine instead of chlorine. Chloramine does not evaporate when left out, it is much more stable.

Quote:
Chloramine is a disinfectant put into many municipal water supplies. In recent years it has often replaced chlorine for two main reasons. The first is that it is much longer lasting, so it continues to provide a disinfectant action in supply pipes, where chlorine typically loses its capacity to disinfect. The second is that it does not react with organics nearly as readily as does chlorine. The reaction products of chlorine and organics (chlorinated organics) are very toxic to people, and water supply operators elect to use chloramine to reduce this toxicity.

Unfortunately for aquarists, dealing with chloramine in tap water is not as easy as dealing with chlorine. The chlorine in tap water can be eliminated just by letting the water sit for a few days prior to use. This is not the case for chloramine, and aquarists MUST take active steps to eliminate it.

Maybe we should all find what our council uses, it would make water conditioning decisions much easier.

I dont know about over there, but here water corp only use chloramine in the Perth - Kal pipeline.
Around metro area they dont use it.

In the US, the water companies are required by law to make the water report available to the public and often times it's even listed with the Environmental Protection Agency here (not many people here know they can look it up). Maybe there is something similar in Australia?

Use sodium thiosulfate or ascorbic acid to break the chloramine molecule.

Seems most country/rural areas or anywhere that has to pipe water over any distance, uses chloramine..

The south aust water place have some info which mentions using sodium thiosulplate, but that leaves water with high ammonia.. doc is here: http://www.sawater.com.au/NR/rdonlyres/D31304E6-B5AC-410B-B6C4-7C2E016FF93E/0/ChloraminesAquariums2008.pdf

Maybe treating some tapwater in a seperate tank while running a small pump and a zeolite trickle filter on it for a while would work?

Get a rainwater tank :)
Just moved into a house with one already installed. I use it to fill my aquarium

Locally I have chloramine water and all it needs is a few weeks out in the sun before adding large quantities to a system. just to show I recently did put about 150L into my top up tank which is set aside to cater for chloramine, the 600L tank was down to about 300L, I added the water from the tap slowly over 6 hours just dribbling into the tank. Everything in that top up tank is alive which consists of blue eyes and a heap of green tree frog tadpoles, the biggest effect i've had from chloramine water is killing a few fish after accidently doing an approximate 50% water change with tap water, my immediate reaction was to salt up to about 4ppm in hope all my fish wouldn't die. I figure it helped becuase I still have most of them :support:

from reading messages here, I'm getting the impression that rain water collection is big over in Australia? Or is that more typical of people in aquaponics? I can see how it would work either way.

Our socialist government had a brilliant idea of giving people rebates to buy water tanks. So lots of people went and bought small backyard tanks to "save water".
I agree with saving water, just not socialism :)
There were also regulations brought in requiring people to have a water tank if you had a swimming pool. So all these pool owning people went and bought these tiny little tanks, really useful !!
Anyway, that explains all the water tanks in Queensland anyway, not sure if the same stuff went on in the other states. The only good to come out of it was that more aquaponicsers and pre-aquaponicsers (me, renting) have water tanks they can use to fill their systems :)

Fair enough, I shouldn't have got on my soapbox :)
I spend a lot of my free time studying Austrian Economics so I tend to see the world through that lense... (my point was not silly or paranoid though, every new form of higher taxes and government handouts or social benefit IS another incremental step towards more socialism, if you're interested I'm always up for a healthy debate :)

Stumbled across this one today, thought you guys might like it as a "kicking off" point for your debate...enjoy!... :thumbright:

Ineptocracy (in-ep-toc'-ra-cy) - A system of government where the least capable to lead are elected by the least capable of achieving, and where the members of society least likely to succeed or even to sustain themselves, are abundantly rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.
