Just some idle ramblings but I don't know why people never mention Lifeguard or Pentair filters(same thing) on this site. They have a nice modular design so that you can customize them more biological, more chemical, or more mechanical whatever. Maybe it's not the filter but the water pump, back in the day Dupla made high torque low gph pumps that would be great for smaller plant tanks today on those lifeguard filters.

Another nice design was the wet dry filters that used rotating spray bars and a special type of DLS material, unfortunately Dupla (again) and people like Albert Theil killed that filter design in favor of those little plastic balls. I remember the first time I saw a marine tank on that DLS design filter and I was blown away by the water quality. Like I said just some idle ramblings.

I know this is an old thread, but I ant to set things straight as I know them. Sorry if this is a hijack. Cino, I have been on Eheim's site in the past month and they are still providing information on the Classics. Additionally I bought a 2215 from Big Al's last week. From what I can tell the Classics are still in production.

Lance is correct. They have improved the ECCO line, but the line doesn't replace the Classics. The Classics are still available.

The older ECCO's has a somewhat different filter design that the new ones. I do not know exactly what all has changed. I have an ECCO 2236 and it is posted that we make sure that we are getting the correct pads.

There was even an older ECCO line several years ago. Their last number was an odd numbers whereas the newer ECCO's last number's are an even number. It could of been 2231, 2233 and 2235 vs 2232, 2234 and 2236.
