It's sitting in 8 inches of water with an Auto Top Off so that depth never changes. I keep the gatevalve all the way open, and there's only one pump! (It's a BM200)
I haven't hooked my air meter up to it yet as I honestly haven't cared what the specs are. With skimmate production like that, what does it matter?
I'm
very happy with this skimmer.
I too wonder why Ronen's skimmer(s) don't pull like mine do. All I can figure is that I use less rock and more flow. I also don't keep a DSB. In Ronen's tank I imagine more waste is trapped in his rockwork where it is broken down, whereas in my tank it's skimmed out before it can break down. Deep's DSB counteracts any "nitrate factory" that his rockwork causes ?
Maybe.
