Everyone on
www.nano-reef.com raves about Remoras.
They are very good skimmers and I really liked this one. But my tank plans changed and I needed an in sump style skimmer.
The best part of this skimmer is its ease of operation.
Hang it on the tank, plug in the pump and away you go. Only have to move the collection cup up or down to adjust for wet or dry skimmate.
The design of this skimmer ensures that no matter how full the collection cup gets, it will never overflow.
As for noise, it is farely quiet. That said, I dont think that a silent skimmer exists.
