the neck gets nastier faster now that's for sure. I'm still working on getting that ac70 going.. I think getting more air in the neck will allow better skim. It's not showing much, probably still in the 1/3cup range, but it just looks nasty. I just added some more clean up crew and another fish.. so now I have 5 in my 45g
, seems like a lot to me, so I'm glad I have the big guy back there.. workin OT!
