My system is together, the only thing I had to do was get bigger net pots today. It's up and running, works great. 15 gallon tote, long but shallow, 160gph pump with veturi (sp) adapter to add even more oxygen, 18w air pump, 2 12" air stones, 2 micro drip heads. My only concern is the drip heads, they are supposed to be able to make a 36" ring of water with adjustable heads. I would want a 4" ring of water but all I get is a steady drip, no ring. The system only rises about 15" so the pump should have the pressure
