That is good that you are doing a sump. With the way you had it, it looked as if you had the tank flush against the wall which made me think you were not doing a sump.
I personally like Catalina pumps. They are not the first brand that I would recommend to customers because they do not have the best reputation (supposedly), but I have never had a bad experience when working with them. On my old 75, I used a catalina pump to run my skimmer and it worked flawlessly until I broke the tank down to convert everything to my current 210. Also, I set up someone's tank with a catalina, and that never broke on them either.
That is the pump that ETSS gives with its Super Reef Devil skimmers. I have never personally heard any complaints but supposedly they have a bad rep.
