Can I ask you a few questions about your setup? Since obviously this set up is for something different then the 10g nano in your signature line. You can do better then either of those skimmers, particularly on a 55g.
What are you planning on keeping in this 55g tank? Do you know what the total water volume would be? How heavily stocked will you be keeping your tank. Do you require an in-sump model, or anything specific to run it?
