It's amazing. I haven't been to the forum since 2010. Crazy.
My closed loop tank is still the same and has been running for close to 10 years now. My Eheim 2222 is as good as new and has been working for the last 10 years with no issues.
Actually I hit a jackpot and literally got a pile of equipment from craigslist add for basically close to free. One of 4 filters I got was Eheim 2226 which I'm planning to hook instead of 2222 but need to mod the impeller to slow down the water from say 760l/h to say 500-600 or close to what 2222 has.
