Thanks. Just wanted to be sure I didn't miss it. Currently, my EuroReef CS8-2 is the loudest piece of equipment on my reef.
If the Tunze performs as well, then I'll get one as it probably will fit my sump better, use less electricity, generate less heat, and work silently in typical Tunze fashion.
Separately, the Altums are still doing fantastic. Great, peaceful fish. It'd be really nice if they spawned one day....
