So I got a Tunze 9012 - and I got it as I cannot do a sump on my 75g fowlr. The problem I'm having is getting it to stand high enough above the tank - I'm running into an issue where the top frame is in the way... Its preventing me from being able to push the unit up any higher...
Where it sits now, bubbles just pour out into the top of the tank. As I read about this, you want to have it only about 1/3 of the way on the grates into the water.. Mines more like 3/4 or more
