Looking for some feedback. In the market for a new RO. Using a Deer Run 500 for the past 6 years. My sap averages 1.4/1.5. Rarely if ever see 2. I two pass now and boil 12/13%. I would like to get that with one pass. Is it possible with one membrane? My local dealer carries Leader but CDL is definitely an option for me. All thoughts appreciated. Thanks.
