Things You'll Need
- Deep sand-bed refugium
- Macroalgae
- Rock
- Coral glue or holdfast tissue
Instructions
Place a deep sand bed in a well-lit refugium. The refugium must receive water from the aquarium's outflow in order to take in nutrients from the aquarium's bioload.
Plant a few pieces of sea lettuce, sargassum weed and/or spaghetti algae in the sand bed. These are fast-growing, nutritious food for herbivores and copepods.
Cut segments of the seaweed and attach to rock with a bit of coral glue.
Place rock with seaweed in the fish tank for the fish to eat. Replace as needed.
Attach spiny seaweed, red grape algae and/or blue ball algae to rock with coral glue or holdfast tissue and place directly in the aquarium. These attractive, slow-growing seaweeds are not likely to take over your corals.
