Looks more like a macroalgae to me.

I Agree Looks like some type of Bubble algae

It moves like jelly in the flow. It has come one pretty aggressively in the last coupe days.

If it is bubble algae it can be a bad nuisance. If they are translucent bubbles then you want to start removing them. It can be a major pain. There are numerous threads on her regarding bubble algae removal.

It isn't the typical green bubble algae. Familiar with that pest. I cleaned some off and it does in fact have the consistency of a gel. Chemiclean doesn't seem to be touching it.

I would pull the rocks out . Scrub them in some tank water then rinse them in another container with fresh ro/di water. Def do not try to clean it off inside the tank . This will likely only help is spread..
