So I've come to the conclusion that it's absolutely necessary to have an RODI System. I figured if I'm going to do this, I might as well do it right.... That being said which do you think is a good RODI system? I'm not trying to spend a crazy amounts I just want to get the job done. I don't even know what the main differences really are considering they should all pretty much do the same thing right? I'm going to be running a 75g saltwater with 20g sump.
