I posted this on Reef Central and decided to post it here as well. Has anyone made the HSA skimmer that is on Creative Reefs site? It uses 1 beckett 1408 injector and sits atop a 48" x 4" od pvc tube and another 18" x 3" od pvc tube . The injector is fitted inside a screw-on pvc cap and has a 48" x 1" pcv tube attached that goes down through the middle of the two pvc pipes almost to the bottom . Seems like a good design , but was curious if anyone has actually built and used one. Would like to try it , but some feedback from someone would be great before I order any parts...If I do decide to make it , I will use clear pvc pipe , even though it is rather expensive..............Thanks in advance....Steve in Va.
