A guy is willing to sell me a reverse osmosis set up that he used a little over a year ago. He had a 75 gallon sw. Is a reverse osmosis set up a good purchase? He will sell it to me for $25. Here is a pic?
Moved to General Hardware and equipment discussion.
An RO is a good buy. A better suggestion would be an RO/DI unit. You can get a seperate DI unit to add to that.
It`s better than tap, dont get me wrong but it`s not as good as RO/DI.
What exactly is an RO/DI?
