First ....welcome to the board......as for the bubble algae.....try the search feature and you'll find tons of info....to answer your question I'd try a couple of emerald crabs and see if they can munch it quicker than it grows...provide more info on your system(filtration/size tank/lighting/LR/LS...water chemistry etc)...the more folks here know the easier it is to advise.....but take my word emeralds like to munch bubble algae
