Good point but not that I'm aware - however I will verify.

I know that this greatly affects my HOB mini Octo in my 25 gal. shallow cube, but my NW150 stays in the sump which keeps a constant level...although I have had a lot of evaperation after adding more fans to keep a more consistent lower temp...so it could play a factor.
