Add bleach to the tank, turn temp up to high setting...
Then after the heater cuts off with a full tank of really hot water run every hot water fixture until you smell bleach. Then turn them off and let the fixtures sit for 24 hrs.
You could also bleach the cold lines including the main coming in from the well or meter.
Consider installing a chlorine injection system.
