Just notice this little thing by the anemone moving really slow, maybe came in one of the rocks , I have no idea what it is and is reef friendly,really appreciate some help... Is a little hard to see it in the picture,just beside the anemone bottom
I'm using a Venturi style skimmer,hang- on and is doing the job very good.
For your 75 g maybe an hang on or in sump protein skimmer is a good idea, most of them can be use as hang on or in sump...
I'm using a cyclone by marineland....
