RO/DI qusetion

[reef165]

Ive got a 25 gpd Ultralife reef product RO/DI and was wondering if I could use a 75 gpd membrain without changing anything? Also If I were to add a second membrain could I use the waste line from the first one to run the second one? Hoping to get more good water and less waste.

Yea this would work but you must have around 50-55psi at the second membrain to get the performance you are looking for I just added a 75gpd to my 75gpd 5 stage from BRS and a 8800 pump I went from around 1-4 waste to right at 1-1 , 1-2 depending on what time of day, You may need to change out your flow restricter also, Try calling them for help, Good luck.
