Let's talk about skimmers

While Vertex recommends that they can be run as deep as 9" my experience is that they do far better in shallower water. That seemed to be the problem with the Omega 130 as well which worked best at about a 6" depth. As I said, they are also quite sensitive to buildup in the volute and venturi too so those should be cleaned regularly. That's easy since the whole thing just twists off the front of the pump.

I also have an Omega 150, quick question by turning out the venturi, am I right in thinking it speeds up the water and air mixture going into the skimmer by increasing the flow length?
