Iā€™ve never seen this before in my tanks and it just started growing in my planted 55 gallon tank. Itā€™s not spreading at an overly alarming rate but itā€™s still really gross. Looks like a plasma or slime. Itā€™s only on the sand.

That's cyanobacteria, aka blue-green algae
 
I'm usually ok with algae but that looks sick... Like a bad sick, gross sick. I have no idea what type of anything that is!
 
It looks like transparent slime
 
Look at it on the sand. That looks just like blue-green algae to me.
Seems too bright and too neon-like. It also looks thick and slimy. I have never seen bga like that if it is.
It looks weird
 
BGA is slimy and you can siphon it out in big sheets
