From marinedepot: Simply place the skimmer on the back of the aquarium, mount the pumps in place as the instructions list and it is ready to skim. This HOB Reef Octopus skimmer is powered by two Aquatrance 1000s pumps and are built with high quality acrylic.
- seems rather simple. What do the instructions say?
I have that skimmer, it should have a min and max water level on it. I have mine right on the max line with the bubbles adjusted to about a half inch below the top of the neck
