I realize I should have posted PAR numbers for a single lamp first. Here are some readings for heights of 18", 21", 24". At 21" height you can have medium light levels in most of the tank. The...

Between my work commitments and final delivery of the sensor, 2 weeks I would say. I work in the film business. It's miminum 13 hours a day on set for me, which basically doesn't give me a life .

Do you mean Albany's ? :) I would agree, it doesn't contain very much info. Frustrating.
