mine does that i also have a vertex in180 its in 8" of water.
I get about an inch in the container over a week or so but the smallest turn and it overflows in 20 min.
I have a small bioload so i figured it was fairly normal since the 8" is the reccomended height IIRC but im sure I didnt guess when I made my stand for it.
so if i run it in say 6" of water you guys are saying I should have a easier time finding the sweet spot?
