Alright this filter stopped working about 2 years ago and while trying to get it to work again I broke the propeler rod. Well I found the part to put it in and it works fine kinda. Now it leaks under the handles on both sides. The prime knob if its all the way down like its suppose to be it leaks to. It has to be all the way up for it not to leak there but it still leaks around the handles. Read online that people put vasaline around the rubber seal which looks like new dont have any vasoline though. Anyone have ever have this problem. Even if I can get it to stop leaking I'm still weary about using it since it leaked once it could again and coming home to water on the ground would not be a pretty sight. I have it on my 150 gallon. I might just have to bite the bullet and get a fx5. I'm wanting to start a african cichlid tank so I'm going to need all the filtration I can get.
