OP, For tank that size, and sump, HOB skimmer wont be good enough. HOB skimmer may be good for 30-40G tanks, but anything over that they dont do good job at all.

Correct. I was hoping to keep more space in the sump for other filtration (rubble and macro algae).

But I read that the octopus 100 was designed to handle tanks over 100g. Lfs had recommended it too. Hope it works otherwise I'll switch. Again, appreciate the input. I've got a lot of reading to get caught up to refresh.

Another question for anyone still following; is 1.4lbs of sand per gallon and 2lbs of live rock per gallon too much substrate? Local store said that more than 1.5" of sand will cause problems down the road
