I just set up my filter that came with the Marineland Eclipse 3g, and the first thing I noticed is that it made a buzzing sound that would buzz for a few seconds, go away, and come back again. I didn't really mind it at first, but then I noticed that it was interfering with my heater!
I use the Elite 25W heater and I noticed that whenever the filter was making its buzzing noises, the pilot light on my heater was flickering in sync with the buzzing.
I have taken out the filter, took it apart, cleaned it, added more water... Nothing seems to be helping. Anyone have any other ideas?
