As you see you will get varied responses.There are several great skimmers out there at the top of the list as far as cost,performance,durability.
I have an ASM G-2 on my 65 and a Euro-reef CS 5-2 on my 75. ASM is a cheaper version of a euro-reef and they both do an equally fantastic job. For design,I would choose the euro reef. If money is tight,get the ASM. They have a needle wheel pump..it chops the water into a finer foam.Good job researching first.
p.s. How do I know these are good skimmers? I used really cheap and inefficient ones for years. Aqua-C is another skimmer I work with..that is phenominal.
