Replacing Skimmer on 125 Gallon
 

My skimmer has just not been cutting it for some time and I'm looking to upgrade. I really liked the look of the Tunze 9410, but its ideal immersion level is 5.5 inches to 9.4 inches. Is there other decent skimmers out there with a lot higher immersion levels? The water level in my sump is 16 inches where I want to put the skimmer. I have to put my current skimmer on square plastic bottles which isn't ideal. The space it fits in is 13 inches long by 11.5 inches wide. I'm not considering super high end ones like Bubble King.
