OK, some of my tubing is clear so it's prob. hard to see. My hydro store didn't have the multi port so i'm using a bunch of to ports until it's in. I have the tube going to drip in the res. and then each wf module has an air tube as well, two of them are green. Once I dumped some water out it seemed to maintain. I'm going to add the other buckets just want to make sure it's working. I also put one of the blue tubes w/fill line on the back side of the res. Don't know if I need to but I might feed an air pump tube to an air stone inside. Here's some more pics. Let me know if this helps. Thanks hound for all the help and time you're taking.

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
