shane if your psi into the membrane is 65psi+ then running a dual 75 would better than one 150gpd

I read that too, making one big batch is better than smaller batches..... Which is why I do it all at once and I'm good for awhile.. Don't have to turn it on for 10 gallons to fill up my ATO.....

alot less work in the long run.
