Water parameters

Temp 76-80 F Temperature

Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.

pH 7.8 - 8.4 potential of Hydrogen

Measuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.

NO3 1-20 ppm Nitrate

While less toxic than ammonia, high nitrate levels (above 40–80 ppm) are important to monitor because they can cause fish stress, stunted growth, and harmful algae blooms.

NO2 <0.0001 ppm Nitrite

It is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia

PO4 0.01 - 0.1 ppm Phosphate

It is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

NH3 <0.1 ppm Ammonia

It is the primary killer of aquarium fish, causing gill damage, stress, and death

Ca 380 - 450 ppm Calcium

Supporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae

KH 8 - 12 dKH Alkalinity

It acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.

Mg 1200 - 1400 ppm Magnesium

It enables coral growth by supporting skeletal formation, assists in metabolic processes, and ensures that calcium is available for corals, clams, and coralline algae.

SG 1.023 - 1.026 SG Salinity

Essential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals

ORP 250 - 400 mV Oxidation-Reduction Potential

A higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.

About Legacy Eunicea Gorgonia

General information

In general, sea fans that comes from the genus Eunicea have knobby protuberances where polyps emanates and protrudes. They usually have dark colored sclerites with polyps that are large and feathery in appearance.

As for the Legacy Eunicea Gorgonia, they are predominantly colored blue violet with red tentacles. This are the water parameters in cultivating Legacy Eunicea Gorgonia:

  • Calcium: 400 – 450 ppm
  • Alkalinity: 2.86 – 4.29 MEQ/L (8 – 12 dKH)
  • Phosphates: 0
  • Magnesium: 1200 – 1350
  • Strontium: 8 – 10
  • Temperature: 72° – 78° F (22° – 26° C)
  • Salinity / Specific Gravity: 1.023 – 1.025
  • pH: 8.1 – 8.4

Diet & nutrition

The Legacy Eunicea Gorgonia are classified as zooxanthellate. This means that they get their primary nutrition from the symbiotic zooxanthellae living within their tissues. However, on top of this, we still recommend you do supplemental feeding by adding mysis and brine shrimp in the water.

Determining sex

A mature tank is highly recommended in propagating Legacy Eunicea Gorgonia. They should be set at the middle or bottom portion of the tank. You can use gel glue or any underwater adhesive to securely fasten their position.

Breeding & spawning

The Legacy Eunicea Gorgonia requires moderate lighting and moderate to strong waterflow.

Diseases

The Legacy Eunicea Gorgonia is prone to cyanobacteria infestation, especially if there is minimal waterflow. In case of an algal infestation, you can clean them by removing the algae with a soft brush.

Origination

The Legacy Eunicea Gorgonia can be found in the waters of the Indo-Pacific Ocean and in the Atlantic Ocean, especially in the USA and Canada.

Cautions

Although the Legacy Eunicea Gorgonia has a peaceful behaviour, proper spacing should observed in relation to corals with an aggresive or semi-aggresive behaviour.

Acclimation process

Legacy Eunicea Gorgonia is purely marine. So, therefore, salinity must be maintained thoroughly at 1.023 to 1.025 specific gravity.
