Mp60 and mp40s vibrating tank.

[Aere]

Hello!

I have a 300g tank with an mp60 on one end. And two mp40s in the other. The tank vibrates. And it's noticeable. I've tried messing with the pumps, I do have the correct spacers. And it still vibrates. Should I be concerned at all with any kind of failure of the tank/seams or anything?

My first reaction is whether the two parts are aligned well. My second thought is maybe the “propeller” is off balance or something like a bent shaft is messing up the alignment. Is it all powerhead s or just one of the three?

I'd check the ceramic shaft to ensure that there isn't any calcium buildup that prevents the prop from moving freely.

Its just the mp60. I cleaned it yesterday. I'll take it apart again and see what's going on.
