I don't have extensive knowledge of skimmers. I have used only two. A CPR Bak Pak (reef version) and now an Aqua C.
Ease of use- pretty decent other than dialing in the water height seemed to take awhile during break in but once set seemed to after a day stay pretty solid.
Plumbing- Id have to say using soft tubing isn't too awfully bad. The fittings all seemed to be well thought out except for a couple that fit a little too closely.
Collection cup- Easy twist and lift to dump. also has a outlet for using a skimmer jug if you want to.
Complaints- only thing that seemed a little tough was needing to see through the acrylic which is smoke black.....need a flashlight. Other than that its nice, the spray injection really does seem to make enough bubbles.
I'm running a Rio 1700 pump on it.
From my limited use of skimmers I give this one two thumbs up.
