I know a godlfish breeder in Auckland who never used additives to get rid of chlorine. I saw him fill a tank from a hose (and I could smell the chlorine) then dump the fish in it. He said he didn't have time to muck around with water and the fish would have to get used to it
Seems they did though as all his fish were huge and healthy.
We do not have chlorine added to our water either so can use it straight from the tap.
I understood there was a difference when speaking about chloramines in the water, as a result of added chlorine, and other chloramines actually added to the water supply. Overseas it seems they add both to the water supply.
