I see them on ebay all the time. Are they just peices of crap or are they decent? I am starting a 60 Gallon FOWLR and im a poor poor college student so I am all about finding a good deal.
I haven't used this skimmer and saw either hate it or love it comments on it. However, I've used an absurd array of skimmers over the years and have built many of my own. Give me an empty 2 litre coke bottle and a good wood airstone and I'll slap one together that will compete with a $300 venturi design. After all, most skimmers are nothing more than plastic cyclinders and fittings. I also consider most of them over-priced and too reliant on insufficient foam generation. Have you see the amount and density of foam crated with a 3" wood airstone and medium sized air-pump? That's what skimmers should be using.
The Jebo looks like a knock-off of a Euro-Reef. I'd take this thing in a heartbeat over a Seaclone.
The design looks decent, but also looks like an in-sump only and not a hangon back style. I suppose you could run it in tank, but it would be butt ugly.
There are really only a couple of critical things that affect skimmer performance. They are dwell time, bubble size (smaller the better), and current flow contact. The rest is mostly marketing. A skimmer's capacity is mostly a product of the pump driving it.
A good choice of pump is what will determine what will make this thing work or not. *By far* my preference is for needle wheel types because they make smaller bubbles than your typical venturi types. I'm sorry if I offend anyone, but I consider *all* venturi_by_powerhead skimmers to be grease off the same meatball and have the same efficiency. I've seen some new designs that have tweaked venturi inlets not on the pump that likely produce finer bubbles, but haven't used them.
So, combine this skimmer with a decent needle wheel pump and it will likely work great. Use it with a standard venturi pump (likely the one sold with the Jebo) and it will match the performance of any other Venturi design - good.
Shame the chinese can't make a knock-off of a EMT design in HOB style. I have a CAD design for one somewhere I made (sorry for rambling)........
