I'm not sure if you're disagreeing with me here.

In a bigger system like what you're talking about it would take a lot of air pressure to interrupt the function of an airlift pump. I don't know the math, but I know it would be a lot. So yeah, you could use just about any normal air pump you find with good results.

GH WATERFARM USERS: SIMPLE RECIRCULATING SYSTEM Ok so I was at my hydro store yesterday and the BRAIN pulls out this kit from GH that makes your w/f set recirculating!! Ordinarily this isn't very exciting news EXCEPT...... Get ready.......:jointsmile: It uses an air pump and drip ring set up to move the water through the system. You do NOT NEED A WATER PUMP! Let me repeat that part: YOU DO NOT NEED A WATER PUMP. IT RUNS OFF A BASIC AIR PUMP. Rating: 5
