Just another bubble algae question

[cruzersmith]

Like God said in Ecclesiastes “There’s nothing new under the sun” I figured someone here had experienced this before. I have added a crab to reduce the bubble algae but doubt it can deal with the 8 or so snails like the picture. I can pick up any that are rarely on the gravel but wondering if anyone has a method for getting them off the rocks and glass. They don’t seem to mind my scraping the algae off with my fingernails and returning them but they have a death grip on everything but the substrate.

Emerald crabs or even better, pitho crabs will clear your tank of the bubble algae.
