How to Rid the Aquarium of Bryopsis

Bryopsis represents a nuisance algae that shows up in aquariums. This algae produces toxic chemicals to other organisms and reproduces quickly and easily. Aquariums usually get bryopsis by introducing live rock into the environment. Certain steps get rid of this annoying algae plant before it spreads and kills much of the aquarium life.

      Freeze live rock for 48 hours. Live rock is rock introduced into the aquarium from a natural environment. It comes with live organisms, which die along with the bryopsis in the freeze. Allow the rock to thaw and brush off visible debris with a stiff brush before reintroducing to the water.

      Elevate the aquarium's pH levels to at least 8.5. Keep the level elevated for at least three weeks to kill the algae. During the first three days of the pH elevation, eliminate all light from the aquarium. Cover the aquarium with reef-safe plastic to prevent any natural or unnatural light from entering.

      Bring hermit crabs into your tank. Most herbivores won't eat bryopsis, but hermit crabs will help take care of the problem. Although they can't solve a serious outbreak, hermit crabs mostly help prevent further algae problems.
