I'll have to go by HMI and see what the specs and media used are. I'll post what I find out if I can find this thread again.
Okay, I went by Hawaiian Marine Imports today(
www.hawaiianmarine.com) and checked on the 2080. The pump output is 1500l or 449gph(US) according to their literature. As far as the media goes, they sell a media kit. they recommend 4 liters of efimech and 8 liters of efisubstrat pro. For those unfamiliar with efisubstratpro it looks like kix cereal. because it's round it doesn't restrict the flow as much as efisubstrat did. It also doesn't collect as much debris.
When comparing the 2080 to the 2260, I STILL prefer the 2260. the output is rated at 635 gph (US) and the media chamber is 1.5Xs the size of the 2080. IMO, the workhorse of the entire line remains the 2217 classic. Unless your situation requires monster filters, multiple 2217s are probably a better value and choice.
There's a pre-filter tray. I've always complained about Fluvals and the fact that dirty water can bypass the media and return to the tank. It would appear, to me anyway, that Eheim is now doing the same thing. Like the Liberty hang-on-the-backs and the Ecco filter line, despite the praises the 2080 has received here, my inclination is to say the 2080 is a step backward in style and performance, as well as the class previously offered by ALL Eheim products. If you owned a Mercedes dealership and wanted to add another car product would it be a Yugo? As a dealer, I refused to stock Eccos or Libertys.
BTW, from what I can figure, a retail price point for a 2080 should be around $600 USD. Eheim North America has pretty much destroyed the tier structure for distributors and dealers, selling direct to almost anyone. If I were a dealer now, (I'm not) I'd have to reconsider any stocking level of Eheim products. Previously, because there WAS a tier structure, I could have matched a mail-order offer in most cases with no loss or sweetened an offer by making the unit complete with media, allowing me to make a few bucks.
I've never been one to promote an entire product line. Eheim, until the last few years had been one of the exceptions.
