Aqua-C EV ?

[USCGReefer]

So I just got my hands on an Aqua C EV Skimmer. Pretty sure its the EV-240 but was told it was the 180. First off is $40 a good deal? no cracks on anything but the skimmer cup which I can fix up.
Secondly, is there a definite way to identify and figure out the model? I've looked up the measurements but doesn't seem to match specifically. Maybe the size changed slightly through the years, its closest to the 240 from what I can tell.
Whichever it is, should I go with the recommended pumps or do they work ok with any pump as long as they have the same GPH rating? Was thinking if I can't fully identify the model, possibly get a DC controllable pump that matches a Mag12(the recommended for EV-240) and then can tune it down if it is too much.

Thanks.

Uh, Yeah, $50 is dirt cheap for that skimmer so long as all the components are functional and in good shape. Those are great skimmers! If the size is the same as the 240 use that recommended pump. Use the pump designed for it. IMHO. Show us some pictures of the skimmer and take apart so we can see the condition of the components.

here are some pics and measurements. I’m pretty happy with it. I’m thinking about plumbing it into the return line. Save space on another pump, save power, and makes things easy.

When I got into the hobby before needle wheels took over those were a top contender. $40 is a STEAL. Running it from the return won't work (probably won't even make bubbles). Those skimmers require high feed pressure to create bubbles. The higher the pressure thru the nozzle the more bubbles it makes. The EV-240 requires a 1200-1800gph pump and the owners manual says it's works best with Danner Mag drive 18 1800gph pump (another dinosaur that use to be highly regarded). This is one of the main reasons they went out of favor.

You can run it with whatever pump you want as long as it is near the same GPH and can handle the back pressure. Back pressure is going to be an issue for most DC pumps.

These are noisy, larger and don't work in cubes, nanos and any tank with smaller sumps - this is why they are not popular anymore with the noobies and front runners that dominate online. People with larger tanks, basement sumps and those who want pure performance need them pried out of their cold, dead hands... but these people are on here too much. One of these can easily outwork a $1000 needlewheel skimmer. They have a strong following, but not like LifeReef.

Agreed, you will need a dedicated pump to get this to perform. As well, DC's lack the umph needed to get them to perform. Like I said, stick with the recommended pump or even the next size up. You can always dial it back. The skimmer looks to be in good shape.
