water treatment for new house

[mariner]

Get a Whole house R/O unit. I've seen em where they come with different size storage tanks. The one I saw in particular had a 50 gallon tank.

Well what ever you choose for the house, the final stage before you hit the tank needs to be DI.

Hi everyone,
I have taken your advice and have Tullocks book on it's way. As I bone up on reefkeeping, I am building a new house. I have a buddy who owns a water softener company and says he can do whatever I want.
I want to know what type of system to have him figure for both our consumption (ie

rinking, washing,etc.),as well as my future reef tank.
R.O.? D.I.???
Thanks...Rich
