MP40 problem

[Butuz]

Guys, finally got water in my new tank (build is under the link below). One of my MP40QDs is making too much noise. The other one is relatively quiet. I tried moving it around a little, twisting, up, down, sideways, still the same. Sounds like a mix of banging and high vibration noise. Quite audible. I used the spacers that came with them using the right glass thickness. Should I try a different spacer (wider or narrower) or do I call Ecotech? Thanks, guys.

can you disassemble the wet side and clean it thoroughly, and check if that resolves the sound. For me, that solved this exact issue

Thanks, I will try that, but these are brand new out of the box.

I have sometimes found some noises will just go away on their own after a day or so.

Have you swapped wetsides to see if the noise 'follows' one or not? If they are new, you may have a defective unit. It is true that these pumps require a break in period.
