Nope it’s still on it.Did you by any chance lose the rubber sole that is between the unit and the glass? That happened to mine. Fell off when I removed the wet side and realize and was at the bottom of the tank.
What do you mean by swell?Check the magnet to see if it is now swollen (from loss of integrity of the plastic case). If and when the magnet swells, it binds to the housing and causes the entire wetside to spin.
It’s a redsea 525xl. I think it’s 3/4inchWhat is your glass thickness?
I have 3/4" glass and the MP40 does not hold on to it very well.
If water penetrates the plastic magnet protection the magnet will rust and start to swell and it will bind in the housing and no longer spin freely.What do you mean by swell?

I had this happenOne of my mp40 wetside is spinning. I cleaned it and now it spins every time I turn it on. Anyone know how to fix it?
It doesn’t have any swelling. The propeller spins freely aswell. Everything works perfectly fine it just spins.If water penetrates the plastic magnet protection the magnet will rust and start to swell and it will bind in the housing and no longer spin freely.
I cleaned the glass already and the wetside itself. Btw this is a brand new redsea tank no previous algae. Still spins thoughI had this happen
It was none of the things listed so far. Clean the glass. Try again
You've maybe already tried this but I'm going to toss it out there as it worked for me. Weirdly, I thought I *had* cleaned the glass, so it took another scraping or two then lining up dry and wet side and then it didn't spin any more.
mine was a nearly new wetside replacement that had that spinning problem (after 1st cleaning)I cleaned the glass already and the wetside itself. Btw this is a brand new redsea tank no previous algae. Still spins though

I run them at 50% short pulse and It spins kind of slow. If I lower the speed down lower then 20% it stops spinning. Ive moved it around to fined the best spot and it doesnt change. It starts spinning fast when I put it up to 75%+.I think that one is 5/8.
On mine with 3/4, mine will slowly spin sometimes. As in so slow that it would take about a minute to do a single revolution, but it's spinning. It usually catches on something and/or fall down a little and fix. Eventually it gets to the point where it sticks fine, even without the magnet.
I've also had times when the mp40 was beating up against the glass. The wet side stuck without the magnet on the other side, and for whatever reason the outside part would bounce off the glass due to the magnets. I turn it off, line them back up and it fixes, but it's pretty annoying. I previously had it with the cord going down instead of up, and it bounced off the side of the tank and hit the floor, causing the bearings to make noise.
If yours is slowly spinning, like barely moving, then you should be able to find a spot where it stops. If it's spinning faster, then I'm not sure other than something is making it too slick.
