If so what's you favored method of removing these compounds? I may have to do this at one or more high schools I'm setting up systems for. I'm calling their respective water suppliers tomorrow to find out what is used.

Hi Cecil.
Depending on the top up rate, we use either activated carbon filters or nothing at all. If it is more just for evaporation and transpiration losses, no filtration is required. It does depend on the amount of exchange. If you can bring the water into an aerated vessel prior to entering the system that will protect from salt accumulation.
Hi Cecil
why don't you use the water from your fish hauling tank?
free from clorin, no need to quarentin and fast/ready cycled.
Then airate top up watter (rain/city) in a barrel as part of the system.
nice to see you back cheers
You could try aerating the water for 24 hrs with and air stone, add vitamin C also is a good deal with chlorine...
All system tests are now recorded at http://aquaponics.scorched-revolution.com/ So if you are interested in my system tests. go there
i saw this a while ago, but never got a chance to look up more info;

oh.. good to see ya around again Cecil
I use a product with the same ingredients as the Ultimate product Keith linked. It works well.
I only treat water if I need it right away and am adding more than 5% new water to a system. We have a small water storage setup that satisfies our ongoing needs for the most part, so treating is quite rare.
Hi,
You can also use sodium thiosulphate granules if you have large quantities of water to clear up.
Be aware that anything that you use to break the chloramine bond will leave you with the ammonia to deal with.
We use rainwater.....so we don't have problems with chloramines.

I would prefer not to use the water from the feed hauling tank (originally from the pond) as IMHO it's a good way to transfer parasites etc. I treat all my fish with a 30 ppt of sodium chloride before adding them to a RAS to implode any external parasites. I don't use my well water for the hauling tank as it's loaded with iron.Originally Posted by ande
Waiting for a call by from the city water treatment plant to see if they also add ammonia as a disinfectant (chloramines) in which aeration is not as effective against from my what I have read in the research.
As I said in response to Ande my research says that is not enough for chloramines -- or it takes much longer.You could try aerating the water for 24 hrs with and air stone, add vitamin C also is a good deal with chlorine...
That might be good but from what I've seen doing a little bit of research, many of these products are not approved for the use with food fish. Granted the fish will not be used for food fish, but I think it'd be better if I come up with a solution that is safe for food fish and aquaponics as an example to the kids if they want to go into food fish farming. (Although I can't imagine a commercial system that could be cost effective using city water).They want to get into aquaponics ASAP btw.
