Customer Review
Works very well
Am using this for my Saltwater aquarium and have it inline with an RO/DI system. It seems to be working very well so far! Very fast shipping too.

RO DI system - Good as new again!
My RO DI system incorporates an Auto Shutoff Valve when the system reaches capacity. I replaced a 100 GPD membrane with this 75. I was a little hesitant due to the GPD difference, but this membrane is performing just fine.From the other reviews, it sounds as if this membrane is not designed or intended to be used in a system lacking an ASV. This was not a concern for me since I have an ASV. Plus this appeared to be an identical membrane to what I had (beside it being only 75 GPD).
