RO systems - whole house or just for the tank

[ekean45]

I'm looking to do one of 2 things. Either purchase an RO system to be used for just for a salt water tank (reef) or possibly add an entire home system so that the filtered water comes out of all the faucets, showers, etc.

I am unfamiliar with the RO filtration systems available and have seem them come in several stages - same as whole house systems.

The following are 2 links to some home depot do it yourself home systems

filter 1
filter 2

Can anyone provide feedback as to their thoughts if either of them would be sufficient vs a unit just for the tank?

Thanks!

I believe the whoke home ones are missing the di part of ro/di water thats used for saltwater. Ive heard it tastes really bad.
