Green Codium Macroalgae

Common names for this macroalgae include: Green Candlestick Algae, Green Saltwater Macroalgae Plant, Green Seaweed plant, Stag Seaweed, Sponge Seaweed, Dead Man's Finers algae, Green Sea Fingers Macroalgae, Green Fleece algae, Felty Fingers Macroalgae, and More.

Approximate Plant Size: ~2-2.5 inches. Shapes, Sizes, and Colors vary.

Recommended Lighting: Moderate to higher reef capable lighting, 8-12 hours daily.

Recommended Water Flow: Moderate to higher water flow.

Description: 

It is considered non-invassive in the aquarium meaning it will not take over. This is a dark green variety and unique shape. This species orignates from the Gulf and Florida Keys. Maintaining proper reef tank parameters (see chart below) is important with this variety as they pull nutrients from your water to grow and thrive in the aquarium.

Saltwater Macroalgae are great for decorative purposes, macroalgae scapes, and nutrient export in the aquarium. Macroalgae are helpful in outcompeting undesirable nuisance microalgae by taking up excess nutrients (primarily nitrates and phosphates) in the aquarium. Hair, turf, or filamentous microalgae in the aquarium is unattractive and can overgrow your corals, rocks, sandbed and create an unhealthy environment in the aquarium. Staying ahead and outcompeting these nuisance algae in the aquarium is the best way to avoid them. Macro algae can be helpful with this as well as good aquarium husbandry and clean-up crew for the aquarium. This species is also great for providing a safe place for copepods, amphipods, and other desirable aquarium microorgnisms to inhabit and populate in the aquairum. 

In some low nutrient aquarium systems or systems with a very established macroalgae population some nutrient dosing may be required for your macroalgae to grow and thrive. We use Brightwell ChaetoGro, NeoNitro (for nitrate dosing), and NeoPhos (for phosphate dosing) in our systems here a few times a week. Every aquarium is different as far as requiring or not requiring dosing and this can change with time. Macroalgae do not handle sharp drops in nitrates or phosphates well and this should be avoided.

Recommended Water Parameters for Keeping Macroalgae:

Macroalgae are full strength saltwater decorative algae. We highly recommend using RODI or distilled water for producing saltwater for your aquarium. Corals, macroalgae and other saltwater live animals can be sensitive to improper water quality or impurities that can come with regular bottled or tap water.

This non-invasive plant thrives under moderate to higher lighting and water flow, making it a perfect addition to your reef aquarium. Use it for decoration, as a macroalgae scape, and for nutrient export, outcompeting undesirable microalgae and promoting a healthier environment for your corals and other inhabitants.
