I'm looking for a protein skimmer to fit inside my Amiracle sump 11 x 7 1/2 x 14 inches. I also have to fit the 3 1/2" Rio pump in there too. 55 gal. FO but future within next month to include corals. Therefore, unless anyone else has any ideas for in sump, I'm looking for a recommendation for an Out Of sump protein skimmer that's excellent, quiet (if possible) , and not outrageously priced. Any ideas?
