Is that a 120v fish pond pump?
I've got a few of them bad asses running skimmers on my reef tank.. they need to prime before they actually start to work.
Yep, it is that pump. I have the res above the pump so I would think it would prime with the liquid dropping down to the pump?
From the manual
PDF:
The pump can be used both in and out of the water.
It is not self-priming and to operate, must therefore be positioned on the outside of the tank – below the water level.
Putting into operation:
To make it operate, suck briefly (do I hear Kreij laughing?) at the end of the pressure hose, until water flows to the pump. Do not insert power supply plug until you have done this. A brief noise when the pump starts up is normal.
As I stated above, I have the res sitting above the pump. When I was putting the water into the res it actually flowed down the tube and started coming out of the top "pressure" tube before I even turned the pump on.
I would think that it should have been primed at that point?
Received the "little" pump that I got for shipping today..........
The little, and I use the word "little" loosely, is about have the size of a dang box of stick matches.
Looked up the make and model and they claim it puts out 61 GPH (gallons per hour) so that should be about 1 gallon a minute which should circulate the system about once every 15 seconds or so.
But wow, what a tiny little pump.
Actually here is the pump the fella shipped me:

Its brand new in the box so I guess I'll fiddle with the Eheim a little more but then I'll put that tiny little dude in and see how it does.
