RO/DI Unit

[Jedi_Master]

I’m currently in the process of setting up a Marine X 90.3 system. I’m stumped on what type of RO/Di unit to get, whether it be 4, 5, 6, or 7 stage unit, whether it should have a pressure gauge on it, and if it should have a booster on it. What do I pick up to test the TDS? Suggestions/recommendations would be greatly appreciated.

I bought the one on BRS it comes with a tds tester I wouldn’t buy a booster until you see what your water pressure is. Or if you even need one. I will add a picture of the one I have has been great. Is there a price range you want?
