i was just thinking about this. i like the shower adapter idea. what i came with was this: to begin with, we are in a drought here in Georgia and we are presently having to water are lawns and gardens with "grey water". grey water is used water from things like the washing machine. a hose runs from the washer to a new garden trash can/bin (its one of those plastic ones on wheels). then we use a sump pump like the ones used to drain a house after flooding to pump it through a hose and outside to the gardens. well what you could do is get a reverse osmosis filter and run a tube straight from your water line (not the washer lol) in your wash room or something into the trash bin (which would remove copper and such for all you sensitive fish ppl) and then all youd have to do is let it sit till it reaches a reasonable temperature - or if your house is too cold get a large aquarium heater - and then you could just get a pump and hose and run it into your aquarium instead of outside like we do w/ grey water.
