![]() I have gone through 6 membranes in my reefing history.
I have always used a dual TDS meter. I have found that the Filmtec membranes stay at 0-2 ppm twice to three times as long as the other ones I have had. I know it is not a conclusive test, but membrane number 2 is working great for me now.
