These little white coils are growing all over my base rocks and my back glass, any idea what they are? I’ve tried picking them off but they won’t budge.

This is a golden color and defiantly gets some bubble shapes. It comes, I clean it out manually and don't have too much problem then comes back.

Hi, I have some GHA, some bubble and another that I’m guessing is sea lettuce? Anyone know what it is. Its quite tight to rocks or maybe it’s the tangs tucking into it? https://youtube.com/shorts/pyItjXE-Z4M?feature=share Thanks
