"Metals can build up in your water heater.  You're probably OK if you flush 
it a couple of times a year.  Otherwise, your fish can suffer depending on 
the metal content in the water that comes from your water heater.

I'm puzzled by all this concern over water from a water heater??

How exactly do metals build up in a water heater?  Keep in mind that a water
heater (at least mine) is constantly being flushed with new water as you use
hot water.  It's not like its always the same water sitting in a metal
container being boiled over and over again for years. :-)  In any case I
have a hard time imagining a water heater slowly "dissolving" into the water
it holds.

I have never "flushed" my water heater.  I don't even think my water heater
has a "flushing" function.

Never had a problem in 20 years of fish (and plant) keeping...

Just my two cents!
