Amazon is great BUT most manufacturers will not give the warranty out I know red sea won't and eshoops won't so if it defective it's at your own risk I had a guy buy on amazon and was expired and came to us to replace it lol and the company said no would not replace suppose the local fish store get it from the big red dog :) what's a few pennies

Fun fact to know and tell: 90 gpd membranes are re-labeled 75 gpd membranes.

Start with 75 gpd Filmtec membrane spec'ed at 50 psi and 77F. Re-label it, and then tell customers your "new" membrane is spec'ed at 60 psi.

Guess what? A 75 gpd Filmtec will produce 90 gpd at 60 psi and 77 F.

We have a calculator on our website where you can plug in the gpd rating of your membrane, your pressure, and your water temperature and see how much your membrane should produce:
