My heater kept falling off the glass so I just left it with part of it touching the substrate. It was like that for a couple months but today when I was cleaning, I noticed the part that touched the substrate has a large mineral build up. I'm using flourite sand.
My theory is that the heater heats up which causes the minerals in the substrate next to the heater to disolve into the hot water then when the heater turns off, the minerals crystalize onto the cool heater. Anyone else experince this before?

Weird. I've never seen it, but I've never used any of the artificial substrates like Fluorite, which, if I remember right, is largely composed of a baked clay.

Have had that happen before. Kind of scary.
