I recently bought an eheim pro series 2 and for some reason the flow is really low. I believe I primed everything correctly and the tubes are fairly short so i dont think theres a clog there. I know that the filter is running low because initally when i have the filter runnning the flow indicator is really high but after a while for some unknown reason the flow dies out. Its almost like the pressure is leaking somewhere over time. Do you guys have any suggestions?
