BUBBLE ALGAE often valonia and dictyosphaeria are somewhat more difficult to control than hair algae because they are not dependent on high nutrients and they fare well under bright light. People have described these species with numerous other interesting names such as green marbles and sailor's eyeball. Whatever you choose to call them, it is likely that a modifying expletive verb will be included if you ever contend with a plague of these organisms. Aquarists have found that bubble algae will either sit quietly without spreading much.... or they positively explode! the natural, deliberate, or unintentional tearing of a bubble can liberate hundreds of seeds into aquarium system. When removing bubble algae manually, it is best to try to siphon the ruptured shell and leaking fluid simultaneously. Diligent control is recommended as bubble algae species are inclined to settle on the skeletons of stony coral and encroach upon soft tissue, causing recession.
NATURAL CONTROL is possible with some key inverts and fishes such as:
ZEBRASOMA TANGS,
RED SEA sailfin Tang, Z. Desjardeni which is considered one of the very best bubble algae grazers.
NASO species is also effective, but only in very big aquariums because of their large adult size.
Mithraculus emerald crabs may be helpful ,WHEN SMALL, for assisting the control of bubble algae but they do not eat such algae to exclusion. In fact, emerald crabs will harrass smaller fish and wreack havoc on desirable plant species. as well as displace and irritate coral with clumsy behavior.
Best way to remove bubble is to promptly remove it manually before it spreads.
