So the algae was touching one of the 2 heads of the mushroom so I cut it to the point only the head not touching it was left and the foot was on a small piece of rock. Dipped it in hydrogen peroxide for 5 minutes. Cut a piece of a frag and put it on there. Hopefully that got rid of it. I'm crossing my fingers.put it on a clean plug or rumble rock.you don't want bubble algae in your tank.
I just cut the ok piece off. While dipping I had a 4 bristle worms come out and some small red dots and it looked like there was possible vermetid snails so I didn't wanna risk it. It was pretty grossI would have scraped it off, and used a toothbrush to lightly clean the plug with h202 before I put it in.
