I have a 5 stage Rodi system with a 150 gpd ro membrane addition on the top of the 75 that came with the system. I only make about 60 gallons a month, so around 700 gallons a year. I have had this system running like this for 2 years now. should I change the top two blue ro membranes? I have never changed those, I've only changed all of the other filters underneath.
I am setting up a new tank and want to have the best water possible. My current tds meter is showing 0 tds when I make Rodi water. so I am not sure if I need to change it or not. should I replace them just to be safe since its been 2 years? here's a pic of my set up, I am talking about the two horizontal filters on top. thanks
