RO pressure

Hello , what is the optimal PSI pressure for 50GPD Mambrane?

 

[Rocks reef]

Optimal is 80psi, most are designed to run between 60-80. The minimum would be closer to 40 but you really lose efficiency.
What is yours currently?
How's your tank doing my friend?

60 - 80

If less than 40psi, add a booster pump.

Rejection rate and production both go up with increase in pressure so running at the high end will be the most efficient
