Taz: I had my share of AquaC skimmers(EV150,200)and found them decent at best. But they are not in the company of say an Aerofoamer,PM, or ER skimmer. I found quite a few small flaws that bugged the **** out of me. 1st being the in-sump installation. To work somewhat consistently they needed to be raised up a few inches and the gate valve needed to be above water level or the skimmer would fluctuate madly. 2nd was the pump situation. Their original recommendation were the Rio pumps and claims of awesome skimmer performance on small pumps. I found this to be a bit exagerated,as I was using a Mag12 wide open on a 150 with the gate valve removed from the output on the skimmer and replaced with one on the actual pumps output instead. Since their "forced injection" nozzle is nothing more than a venturi realistically, I found it also true that a much larger pump drove the skimmer considerably better. And over the last year AquaC now adds in mag drives as "optional" pumps on their website. Another quirk is dry foam production, couldnt get it regardless of pump used or adjustment,and I think this was also brought up in a recent test,and in my case many times I would come home and the skimmer would be overflowing piss colored water. Also a unit I sold off a year ago to a local gentleman has developed cracking around the riser tube base, and there have been a few other reports of this too over the last few months. Seems like there is/was a problem with the quality of the acrylic used or the weld used for the seams. Considering how many units AquaC makes I am sure its no biggie, but it still raised an eyebrow with me. I know AquaC adressed some of the issues which I feel is great, the big one being the gate valve return being raised up a few inches, but it still didnt cut the mustard for me. I found quite a few other brands to be true PnP out of the box with much better performance overall and no tinkering needed unlike the AquaC models. Others may disagree, but this is from my own experience going through over a dozen different skimmers over the course of 2 years.
