I guess I can finish the full initial evaluation. Keep in mind that this thing has been running for only 5 days and "Mr. Speaker, I reserve the right to revise and extend my remarks for the record."
Overall, big thumbs up. I went into this with low expectations. Especially when I unpacked it because the construction materials used don't give you a warm and fuzzy feeling (cheaper grade plastic's all around when you compare to say a Berlin or Turboflotor) and trust me you aren't going to mistake this skimmer for an 8' tall, 4 head Beckett skimmer. This skimmer is in the class of CPR SR series, Berlins, Urchins Pro, Turboflotor's etc and for ease of use, compact size and performance it is definitely at or near the top of the pack so far.
I basically plugged it in and forgot about it. Occasionally when I walked past it I would give it a little tweak here or there. It didn't produce skimmate for about 36 hours but when it did kick in it was a bit too wet and at 48 hours the cup was half full but with a nice brown light brown liquid. I emptied the cup and tweaked it to dry the skimmate out a bit. Slowly adjusted it over the weekend and it had some nice skimmate in the cup when we closed last night.
It is being driven by a Mag 7 pump. I may eventually toss a 5 on there to see if performance suffers, but the Mag 7 seems to be the best and is the recommended Mag pump by Kent. Supposedly the 2100 and 2500 Rio's work as well. I put a Mag 9.5 on it and this worked, precariously (huge almost inevitable chance of flooding with this pump), the bubble size wasn't any smaller nor were there any more so I switched back to a Mag 7.
So yeah it isn't built like a battleship, but damn if doesn't seem to be getting the job done at a reasonable price. We have it on a 180 gallon holding system and I think it will handle this system just fine. I think for most hobbyiest's tanks it will handle 50-120 gallon systems just fine, though most people with larger tanks will likely want to upgrade to a higher performance skimmer. The true test is a long term one, with heavy feedings and whether or not it can export enough to keep problem algaes from starting. Only time will tell. For a real workout maybe I'll make it help cure the next 450 pounds of rock we get in.
I'll post some pics of the skimmer in operation tomorrow.
