Is there a calculation to get the correct pump size for your particular setup? I am making a hydro setup for a SOG with 70 stations.

Rhizome's calculation for fan size in Noob's Growroom Setup really helped me when I was picking out my fan and could use some help with my pumps.

Also...is an airstone needed with an nft system with pump on 24/7?
