Don't think too many people in marine hobby use UV water treatment, but the vast majority do use RODI water for mixing fresh SW & top up. Given the choice between spending $500 on UV treatment as opposed to $250 for a quality RODI system, I'll bet most folks in the hobby would choose the RODI. A side benefit of having a RODI system is having pure RO water available for drinking, cooking, ice cubes, making beer/wine/soda pop, topping up car batteries, radiators.....
