Sorry the links are about as close to an id as I can get. For control/removal the best way would be to remove the rock pull them off out side the tank rinse really well with tank water and put the rock back, then continue this again if necessary. If you cant remove the rock then use a siphon hose, point it right at the algae close, and as you remove the algae use the siphon to suck it out. This will help to remove any possible released spores as you pull the algae.
