On the subject of sumps and pumps, did I mention that I have two buckets in the area with a water level triggered sump pump in it?  This is really useful too.

When I'm cleaning a tank with a large number of fry in it, I siphon into a 5 gallon bucket.  After the water clears, I can shine a light in to make sure I haven't caught any fry.  When I'm ready, I just dump the bucket in the sump system.  The water level rises, the pump turns on, and drains it out through a dishwasher attachment in the sink.

Of course, using a pump to draw seasoned water from a sump is only one step behind what I did, so beware. :-)  Instead of a sump pump, I use a pressure pump normally associated with RO systems and a bladder tank.  That way I just have to turn on a tap and have prepared water right there.

As for chloramine, I believe the majority of water supplies for larger populations in the US are well and truely loaded with chloramine now.  Simply aging the water does absolutely nothing because it is in a stable state.  I've heard of people putting water with chloramine directly into a tank and having the tank absorb the hit somehow, but usually this is from other people who didn't know that aging chloramine contamintated water doesn't work anymore.  They were used to aging water which allowed the chlorine to outgas into the air.  Having a lot of plants seems to be the key as plants do seem to break it down rather readily to get to the nitrogen in the ammonia part of the chloramine molecule.
