I am looking to replace (possibly) my Coralife Skimmer on my 120g.
I would like a HOB
skimmer that preferably has an external pump versus a pump that sits in the water. However, if that is not possible, I would like the lowest and most efficient pump.
This has been a FOWLR
tank, but I may be adding some corals in the near future.
What would be your choice of a skimmer?
