I have no problems with the Coralife skimmers, they work and work very well. I can't see spending twice or three times the amount for a skimmer that would produce the same results. All my tanks thrive and these skimmers produce an amazing amount of gunk or whatever the technical term is, either wet or dry skimming. I would rather spend the money on lighting, LR and livestock, kinda falls back on my $84 frag tank post from several months ago. This seems to be somewhat of a "snob" hobby where people are driven by the best, latest, most expensive etc... I opted to downgrade the Neptune system for the JR simply because it was suited for my needs, skipped the Ego driven urge to purchase the Tunze and opted for the Seio PH's and controller, just making an informed decision on performance of these two brands, I saved about $500. That amount of saved cash is going to pay for some seriously sweet micromussas or monti caps or better yet a chalice that I've been dreaming about.
