Thanks, what do you mean ratio of 2-2?

2" intake / 2 - 1" returns

Oh OK so actually you have a 2-1 ratio relating to area (2^2 : 2x1^2)

Actually now that I think of it, it's really a 1-1 ratio related to water volume in & out. I might be totally off here because of an 19 hr day yesterday.

Yeah, the OM will be over the sump, kind of like that

Grizz, what was the reasoning behind leaving the closed loop down for the first bit after starting up your tank?

It was blowing my sand all over the place because I didnt have my Loc-line in yet and it gave the sand time to settle a bit.
