If you can manually remove the bubble algae, that's the best way. Just be aware that any bubbles popped in the removal process may release spores.
I took a rock out, removed bubble algae, rinsed, and returned to the tank, and weeks later, the bubble was back and worse than before.
Someone stop me! Please! But... not just yet...
