Mp10 dry side bearing noise

[Skuba]

So since reeflink controls my
Mp10 I've been
Doing a short cycle of nutrient export at night, still unsure if its beneficial with only 1 mp10, and only in this mode I hear loud
Friction noise from
The dry side and the motor feels warm. Assuming that's the dry side bearing?

It could be.
I have a slight friction/rubbing noise from one of mine and it's the end cover rubbing on the magnet.
I just replaced the bearings in that same unit since they were noisy too and I had it apart.....$6 each, and very easy to do.

Which end cover? Also which bearing did u use. I remember a thread showing a few. One being ceramic. One steel I think. I know one was more silent but didn't last as long

The end cap that goes against the tank, mine is a little concave and it rubs on the magnet.

I went with regular bearings, not ceramic. I took mine apart, got the part number off the bearings, went and got them, and installed them. Huge difference with the new bearings, absolutely dead silent.
