I received the stirrer bars. They are actually magnetic. I expected them to be plain metal
No worries as they still work with my setup
I grabbed some long screws from our assortment and was able to adjust the distance between the hard drive magnets and the stirrer bars so they are quiet enough and work properly
The other nice thing is the magnets can't lift the fans against the doser containers as the screws are there to stop any movement
Having these mixers running has stabilized my Alk and Ca levels, so I'm very pleased
And even though it wasn't planned as I had these fans in a box, the LEDs are a nice 'ON' indicator
