They used to just sell the magnet, however there were balance issues, much like you would have the tires on your car balanced, these wetsides have to be paired and balanced
correctly.

As much as I love these powerheads, I’m having a rough time trying to justify paying another 200 to replace it.
On thing I noticed in all this is that I have 1/4” glass. That means I could use either the medium or thick spacer. In hindsight, I would now recommend only using the medium one so the magnetic bond is stronger. I don’t think the thicker spacer is appropriate as it doesn’t stay up as well.

That's a toss up, when you use the thinner spacers, the magnetic couple is stronger which holds it tighter to the glass, but puts more pressure and wear on the bearings and bushings. If it were me I would choose the thicker spacer to prolong the life of the unit and utilize the
mounting kit to hold the dry side on the glass.
