RO, or RO?

[Makaiveli]

Are we referring to Reverse Osmosis water, or Real Ocean water?

I refer to Reverse Osmosis...sometimes I'm not sure what heads are talking about

Reverse Osmosis is the most common reference for RO.

Yup...real ocean water is usually referred to as NSW (natural sea water).
