Was the meter calibrated and were the readings adjusted for salinity & altitude and was the meter "at rest" before the readings were taken? (Just wanted to be sure) You can't just turn it on and start taking readings as you probably know.

Are you running both systems 24/7 or only part of the day? What were the water temps when you took the readings?

I see the size of the pond, and the max depth. Where are the diffusers placed, and how many are there?

edit: I see you're running 3 diffusers. Are they grouped together or spread out? What size is the air supply line?

I think once you see the numbers that Ted has, you'll be suprised.
