I have had a Biomaster 250 for almost 2 years. In that time it has been fantastic, easy and reliable. That is until recently when the flow was impeded and a loss of fish.
I have rebuilt the tank and cleaned every part of the filter. With some difficulty, I got it to prime.
Now I have just done a water change. I used the prime pump and water syphoned into the body of the filter. But then the air was bubbling out of the intake. When the bubbling stopped so did any flow. I did not see any flow from the Eheim spray bar outlet. Physically blocking the inlet with my figure and pumping would get the flow running properly.
I am feeling that the priming pump may have failed it just has little flap valves. I could replace this but I don't want to be wrong. Up to now it has been the easiest filter I have every worked with.
