i'm not sure if i should get a ro/di unit. why exactly would i need one of these? do they truly benefit a saltwater system? i don't exactly have the money to throw around right now, and there are other things that i would like to spend money on like new lights, but i was just trying to get an idea of some stuff that i could use. any help is appreciated. thanks.
