ok so i just got my new magnum 350 pro system!!! i WAS so EXCITED! but then i plugged it in...the very first time it was SILENT i almost cried becuase i was so happy....then i noticed it was leaking...so took off the lid and refit the o ring...and woo woo it didnt leak. but the noise and air problem started. i have picked it up turned sideways and i dont know what to do anymore...im so mad and dissapointed that i want to throw it out!!!!! the whole reason of getting this thing was to keep up with my cichlids and to have a silent filter! so can anyone tell me how to get the air out? i think it will stop the noise...or at least i hope. thanks for any help you can give.
