Ageing the water may not help you with chloramine. Before the chlorine can
"gas out" the bond between it and the amine(ammonia) must be broken.
Furthermore, the amine will not gas out. You best bet is an inexpensive
additive that will greak the chloramine bond and remove the chhlorine and
ammonia.

I hope this helps.

Does anyone have experience in ageing water in the blue barrels (30 or
55 gallon) until the chlorine/chloramine is dissipated to a level safe
for fish? I wish to know if this is possible with a barrel with the
bung hole open and how long it takes for the water to be safe.

I am in San Jose and some of the water is chlorine treated and some is
chloramine treated.
