I like MFK for getting information. I also use the internet, but I don't use Google to find information. It was good for that once, when other search engines sucked or didn't exist! (I think it was maybe years ago), but compared to the alternatives it sucks now, imo.
Using Google, it was very hard to find the capacity using the phrase
"Eheim 2217 bio media capacity"
I gave up. Google seems less concerned about giving people the information they ask for than other search engines. This has been true for quite a while.
Using other search engines it was much easier. DuckDuckGo for example had the correct and exact answer in the second thread. Bing had the same link as it's third option. Google had it 8th.
This isn't unique in my experience.
I found that trying other search engines works best when the one you use sucks.
And imo Google is nothing like MFK or any decently run forum. Google is a giant phone book with a slew of unverified, unchallenged opinions scattered among some facts. Unfortunately, as noted above, it's not even a well organized phone book anymore.
