What external pumps do you like for your 500 gallon plus setups? Energy efficiency is a plus
Thank you
Thank you



In general I use Eheim pumps. Small, powerful and reliable.
But for my large tank I use a Japanese Iwaki, with a Jebao as backup.
can you run the Jebao externally? I have a lot of them running now. Pretty sure they say for internal use only


Think it is actually written on the pump. Mine are also all dc if that makes a differenceYes. Er, well. My one is external.
Don't use it all the time, as it is a backup, but I have had it running for a couple of week one time without issue.
Can't see anywhere on the box where it says anything about internal or external.
I did get the AC version (ACQ-12000), not one of the DC pumps. It was cheaper, and I think you get a bit more head with the AC version.
Maybe you can read the instructions and find out.

thank you for looking. I have five or six of these sitting in the garage as backup pumps. Will try to take a look at one this weekendYou have got me thinking now. What if my backup is not functional as a backup.

Nothing is printed on the pump itself. And the manufacturer's web page for the product does not say anything.

In fact, I have been through the entire website, and I cannot find anything to say about either internal or external.
