The cavalry has arrived in my battle with the last remnants of cyano:
This is the only skimmer that is rated for my size tank and will fit my refugium properly while still allowing me to still replace the filter socks.
So, for a quick first impression of the unit:
Interesting how this does not come with any form of proper manual. The only thing the pamphlet says is to "install as shown", which shows a very basic drawing of the unit. Even IKEA does a better job at explaining what part goes where. Also, the package material is very weak. The Styrofoam comes apart very easily and some of it had broken off and gotten stuck inside the pump housing. For the price of this skimmer, I'd expect a good solid box and a professionally printed manual.
The unit itself is solidly made. I think you can use the cone as a weapon for intruders and do major damage to the opponent with minimal damage to the unit. The collection cup is a bit weaker, but should hold up with daily/weekly handling.
The controller looks nice with bright LED's for speed settings and on/off switch. It is clear all R&D and manufacturing money went into the unit itself, rather than the packaging, which is what matters most.
The pump is silent, so silent that at first I thought it was broken until the bubbles started to appear. Even at max speed the pump itself makes almost no noise. The same cannot be said for the air intake which gurgles at high speed settings. I have read before that this is a common problem that can be resolved with mufflers which I'll look into. Still, I am happy I don't have the problems one of the other ReefCentral members has with the unit. I installed mine at about 6.5" water level and it runs smoothly.
The amount of bubbles produced by this unit compared to my Marineland Pro 100 skimmer is enormous.Where the marineland produced maybe one inch of bubbles above water level (when starting up), the DC1 produces easily 4 inches and the smooth cone shape really helps condensing the air bubbles. I can't wait to see the goop that'll come out of this thing once it has broken in.
In addition to the skimmer another inhabitant made it into the tank.

I ordered this little guy/girl as a pair, but unfortunately the other one arrived with a severely sunken belly and did not survive more than a day. Concerned about the health of his/her mate I put this one in the main tank to allow it to hunt for copepods which my QT tank has very few of. After a day his/her belly has filled up nicely and I am confident (s)he will pull through the ordeal and survive.
The nice thing about MarcoRocks Key Largo rock is that they are so porous that you won't need a copepod farm. There's plenty of space deep inside the rock where copepods can reproduce without fish being able to reach them.
