How much caustic soda to add to neutralizer tank?

My house has a Kinetico water softening system. The house also has a 30 gal neutralizer tank and a 45 gal retention tank. Well water ph is around 4.5 Presently I add 8 pounds of soda ash when I refill the neutralizer tank. I'd like to switch over to caustic soda. Can some one tell me about how many gallons of 25% (red cap) solution of caustic soda I need to add when I refill my tank? Thanks for your reply, George

Sorry I can't, but I will say you should have much more retention (time) than that 45 gallon tank can supply. If you're having trouble maintaining the correct pH, that is a more likely place to look than in changing chemicals. I think you may have about the same problem with caustic soda. I assume you don't have any type of mixer to mix the solution in the water line after your solution feeder pump has injected your manually mixed solution.
