Hi all. I just bought an Eheim 2071 Professional 3 250 Filter. Priming is supposed to be really easy but I found that I had to pump the primer button for ages before the filter filled and then I had to carry on doing it once turned on in order to get the water to eventually start flowing. At no point did a real syphon start while priming. I had to pump all the water manually using the primer button from the tank to fill the filter. Each time it looked like a syphon would start it broke....looked like the diameter of the tube is too big to form an effective syphon. have got it going but it took a while. Anyone know if I am doing something wrong?
