Hello all. I've just received my first skimmer and am left with a couple questions that I'm sure the answers are already posted but I couldn't find them.
I got the Octopus NW-200 and am wondering about water depth it should run in. I recall some discussions here about 8 to 9 inches, but can't remember if that was for another size skimmer. I'm also not certain how to adjust running depth other than a riser platform in the sump.

The other question I have is that it appears the pump has just a regular impeller, not a
needle wheel. Are the neddle wheel impellers available for order by themselves somewhere?
