Awesome thread. I luv R2R.
My main skimmer is a (now-)classic Aqua C Ev90.
It's an ever-so-slightly-smaller version of the current Ev120, but without any of the fancy air control - this puppy runs with the air wide open all the time. It's technically undersized for my system, so I've capitalized on that air-draw by over-driving it with a larger pump. Wet skims
like a beast and I use no valve or plumbing of any kind on the exit. It's just sitting in the "correct" depth of water, as defined by experience. I can skim dry by lowering my sump water level by about 1-2 cm, or a little wetter by raising it 1cm or so....but I rarely change it. Maintenance consists only of emptying the skimmer bucket about once a week for me. No sludge cleanings needed -
thanks wet skimming! After bigger tank cleanings, it can generate a phenomenal amount of "nice" skimmate, so I do wish I had room for a bigger drain container.
My backup skimmer for the rare occasions my main has had to go off line is the even-more-oldschool Oceanic "Plus Series" Model 6. This venturi skimmer runs on an Eheim 1250 pump. Pretty underrated for my system, but I still have to say it's performance is impressive.
Atb 1050a it's a solid skimmer. Pulls a good amount of gunk out when dialed in. Fairly easy to get wet or dry skimmate. But as I become more knowledgable I feel that a skimmer is only a small portion of nutrient control.
+1 Many (most? all?) come to this realization sooner or later.
My reef creations mr 2. Seems to get the job done good. Have been considering getting something a little more energy efficient. I have a mag 18 running it. Wouldn't mind having a nice cone skimmer. They look nice, just haven't made up my mind which one I want.
Have you tried a smaller pump on that skimmer? They suggest a PanWorld PS150, which is an 1100gph pump from what I read. Even if you stay with Supreme and get a Mag 12 (110 watts), this change alone may save you all the power/heat that you're looking to save.
If I were you (and pump efficiency was your only beef with that skimmer) I'd be at least tempted to try running on a more efficient pump like the
Quiet One 5000. I run my AquaC EV90 skimmer on the 2200 model in place of a Mag 7, for example, and I stopped needing to run a fan during the day for cooling. YMMV of course.
It may or may not work since the Quiet One is not really pressure rated (per se) and you're encumbered with that Beckett foamer, but as I said I'd be tempted to try as the Quiet One is still "50% larger" than the recommended pump or the Mag 12, but is only 115 watts. That's 1/4 off your power bill vs the Mag 18.
There's also no reason you couldn't run the any skimmer on a timer for only 2/3 of the day and chop off another 1/3 of the power bill. Skimmers will catch up quickly in this scenario - no net loss. In most cases I'd pick daylight hours for it to be off.
Cones are a gimmick, IMO, like tail fins on 50's cars. (Nothing against cones or tail fins!! Just sayin' a cone is a cone and a tail fin is a tail fin!) Having a cone shape does not necessarily make a skimmer a good one - I've even seen a few "boo's" in this thread.

In practical terms, a cone holds less water than a cylinder of the same diameter - this has to be accounted for somewhere else in the design or you get less skimmer per footprint. To me, it's a little mysterious where this accounting happens in many cone skimmers.
If you decide to look elsewhere than your MRC anyway, but still kinda like the "high-flow" type design, then an
ETSS or
Aqua C EV series would both be sensible choices to consider. Both should be able to run without problems on very efficient, commonly available pumps like Quiet One's, or even more expensive pumps.
As others here have said or implied, needle wheel skimmers do tend to be a little easier to dial in for some scenarios and for some users, and most are probably a little more stable overall in performance. (Mostly due to lower overall water flow rates.) If you want to go that route, I would suggest that you consider a
Reef Dynamics or similar. Proven (and still improving) design, copied more than any other. If budget says "no" to a new one, either save up (yes, old fashioned) or shop for a used one. At least that's how I'd play it. Include "Euro Reef" in your searches as these are the same skimmers - the company changed management and names a year or few ago.
If you happen to feel inclined toward something imported, I'd look at Tunze's line of
Master DOC skimmers. Still one of the smartest designs I've seen, and their pumps are primo.
Coralife super skimmer 220 body with a sedra 3500 pump. Works like a champ.
That is a skimmer with style! I like it!
My skimmer always goes nuts when i change socks.
People, let this be a lesson! Stop changing your socks in the tank!
What did you expect from putting your feet in your tank?! :xd:
Brand new etss 700xr with a little giant swc40 pump and a bubble magus nac7
Nac7 is easier to tune. Supposedly the etss will work better but seems finicky.
Anyone have experience with these that can help?
Not finding that Little Giant pump you mention listed anywhere - you have specs?
The ETSS should be a pretty nice skimmer. They are a little particular about installation, but if those requirements are met they should be strong performers. Do you have a thread started on this that you could PM or post? Or just PM me if you want.
Certainly you should have followed all the advice possible in terms of pump recommendation and the advice in their tuning guide (all info therein is dead-on true and good advice, IME on their bigger skimmers):

If I can't build it, I don't need it
Awesome! What was it like tuning this beast when it was coming online?
