My FR Owners' Manual advises to: mix 1/4 C liquid household bleach with 1 G of water and add to FW tank at rate of 1 G of solution to 15 G of tank capacity. Fill tank with water. Open faucets until water runs freely and then re-fill FW tank. Let sit at least 3 hours, drain and flush. Repeat until chlorine smell is gone.
