Hey hound. The pump I have for the res. is just one of the one port little pumps, I think somebody called it a "weeney" pump. Then on the waterfarm modules I have three "two port" eco air pumps. I just didn't want all of the modules on one pump in case the pump goes out. Then none of them would be dripping instead of just the one that goes out. I don't know if that will affect it or not. Each module seems to be doing fine as far as dripping. I think my issue is recirculation right now because of such varying numbers. Would having one of the other pumps like yours for the modules affect circulation also or is it just to pump from the bucket up through the drip ring? Hope this info helps hound. thanks again.
