Not sure how to remove this algae ?!

i removed the first bubble but now I’m not sure how to remove this one. The first was on a coral so I remove it outside of the tank. How should I remove this one ?

Can you get a small pick type tool down into that area and just pry it off without bursting it? Then use a small siphon to suck it out.

Make a siphon from airline tubing with 1/8” hard plastic tubing on the end. Start a siphon into a pail that you’ll toss when done. Start siphoning with the pumps off and if it bursts in the process then all of the spore will be siphoned out of the tank and not spread in your tank. It has worked for me.

Do you have any emerald crabs in your tank?
