Noisy Vortech, troubleshooting ideas?


Recommended Posts

Bought a brand new MP10 QD not too long ago. I put it in my tank for the first time last night and it was making WAY too much noise. I’ve been researching forums and I know to expect some noise, moreso when it’s breaking in, but this is really loud. It almost sounds like a jackhammer. 


Im pretty sure it’s the wet side assembly that’s causing it. The dry side was practically silent when I briefly ran it by itself. I took the wet side apart and examined all of the parts, I couldn’t really notice anything that may be causing this rattling/jackhammer noise. I reassembled it, put it back in on constant speed, and tried moving it around like the manual suggests. No change in noise regardless how much I fine tuned the wetsides placement. 


I plan on contacting Ecotech during the week if I’m able to find the time, but I was curious if there was anyone who might offer some experience or insight into this issue. I’d rather not go through the hassle if it’s something I can fix on my end.

Sometimes the wet side starts to spin and vibrate make sure that the glass on the inside is very clean.


also how thick is your glass?


Glass is 1/4”. I cleaned it on both sides and tried using the spacer just for the heck of it. I didn’t notice any noise or vibration difference unfortunately.

Video? The sides need to be aligned. Should be totally silent under 50%.

I’ll keep trying on the video it’s not uploading through my phone. I have it at 50% constant speed, super noisy. I messed with the sides alignment for a while and no change at all.

Also, I took the wet side apart and inspected the ceramic shaft, it doesn’t look damaged and neither does anything else in there. 


I put the impeller back in the housing, but left the nozzle off. I gave it a few flicks with my finger and it’s making a ticking noise with each rotation. It’ll rotate quite a few times before stopping but the rotating is lopsided it feels like.
