Reef Central Online Community - View Single Post - How much of a benefit is there to flushing an RO membrane?

Well, I decided that since I already had the valve it would only take a little work to get it connected, so I went ahead and spent 20 or 30 minutes connecting it and programming it and testing it.

I discovered that BRS sells an auto flush valve and theirs will flush the membrane for 18 seconds of every hour the RODI runs, so I figured that was good enough for me. I programmed the apex to open my valve for 18 seconds every hour whenever my RODI is making water.

I have no idea whether it will make a significant difference in membrane life or efficiency, but for 0 cost (since I had everything I needed laying around) and 30 minutes of my time I figure it’s not going to hurt.
