Baking soda will work fine but if there's a high concentration of chlorine, it will take a huge amount of it to neutralize it.
I had the same problem with a 550 gallon spa. No amount of baking soda would lower the concentration (which was off the scale) but a 1/4 cup of hydrogen peroxide completely killed it in 5 seconds.
