RODI water question/filter

Good graph. Since your tank is a 55, you should be ok with the 24 or 50 gpd membranes. But you know your tank and your water isahes better than anyone else.

Remember that unless you have factory spec pressure and temperature, you won't get the rated membrane capacity. For example, with a 50 gpd membrane, 55 degree water, and 42 psi, you'll only get 27 gpd:

Because there is little price difference between a 24, 36, 50, and 75 gpd membrane, most people opt for the 75.
