YOur best bet for bubble algea is manual removal. Try not to break them in the process. This type of algea spreads quickely. Maybe try a new PO4 test kit to verify if yours is reading correct.

I don't think the snails are going to go after the bubbles. More emeralds might help. Your total fish load is a Yellow Tang? What and how often do you feed it? Are you feeding your corals at all? Have you tested freshly mixed saltwater for PO4 or NO4? Try that and are you running any carbon? If so what kind? Good luck.

I also have these fish:

1 Clown
1 Coral Beauty
1 Royal Gramma


Oh, and I also have a Queen Conch

I have tested fresh mixed water all was good

I feed the tank once daily with frozen mysis and a seafood mix type food
I drain the water off before feeding, I also feed Reef Snow every other day.
