I am gonna be changeing a few things around soon...I just drilled my new 33 long sump with (2) 1 " bulkheads so the pump will not loss its prime...may us my other 33 long for a new refugeium...still thinking this all out.
to me you have too much going on there, too many hose's and lines. and id get rid of that skimmer, also doesnt look like you have any gfi's on there as well
