Not all RO units de-ionize. The De-Ionizing is performed by a special cartridge that is connect to the RO unit. You'll know if the RO unit does De-Ionizing if it is an RODI unit where the "DI" stands for De-Ionize :-). Although, some people do use the term RO in a general sense even if the unit does de ionizing as well. Confusing, I know. It is best to ask the vendor if the specific unit you are looking for does DI.
You don't need a marine grade one. Actually I didn't know there was even such a thing. You can use an under the counter unit.
