Temperature
Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.
pH 7.8 - 8.4 potential of HydrogenMeasuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.
NO3 1-20 ppm NitrateWhile 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 NitriteIt is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia
PO4 0.01 - 0.1 ppm PhosphateIt is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.
NH3 <0.1 ppm AmmoniaIt is the primary killer of aquarium fish, causing gill damage, stress, and death
Ca 380 - 450 ppm CalciumSupporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae
KH 8 - 12 dKH AlkalinityIt acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.
Mg 1200 - 1400 ppm MagnesiumIt 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 SalinityEssential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals
ORP 250 - 400 mV Oxidation-Reduction PotentialA higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.
About Metallic Green Galaxea
General information
In general, corals from the genus Galaxea have corallites that have different sizes in just a single colony. Their polyps are usually exposed and extended out and usually has a milky white tip which is a unique feature for all Galaxea corals.
As for the Metallic Green Galaxea, they are predominantly colored reddish purple with green polyps. This are the water parameters for cultivating Metallic Green Galaxea:
- 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 Metallic Green Galaxea get its primary nutrition from a symbiotic algae called zooxanthellae that is living within their tissues. However, we still rcommend you do supplemental feeding by adding mysis and brine shrimp in the water.
Determining sex
A mature tank is highly recommended in propagating Metallic Green Galaxea. They must be set at the middle or bottom part of the tank to simulate their natural wild environment.
Breeding & spawning
The Metallic Green Galaxea requires moderate lighting and moderate waterflow.
Origination
The Metallic Green Galaxea can be found in the waters of the Indo-Pacific Ocean, particularly in Japan to Australia and Egypt to Tahiti. They are now listed as a threatened species under Appendix II of the CITES list.
Cautions
The Metallic Green Galaxea has a aggressive behaviour. So proper spacing in relation to other corals must be observed.
Acclimation process
The Metallic Green Galaxea is a marine species. Therefore, salinity must be maintained thoroughly at 1.023 to 1.025 specific gravity.
