yup, the 2 flex hoses will T back into a single 1.5" at the bottom of the spray bar then I will just hang it on the back of the tank and its own weight should hold it in place. Nervous about what my "actual" head loss will be I am hoping for somewhere between 6-8' which would give me around 1200gph through each ultima. If not a pump upgrade may be in my future lol
