I am in the process of setting up my dry cell, I have most of the components. My question is this, I was planning on having my reservoir gravity feed the electrolyte to the Generator. I've seen some setups that have a shurflo water pump pumping the electrolyte to the generator.

1. What are the benefits of this?
2. Is using a pump preferred?
3. What would the recommended max gph of the pump be?
