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 Green Bubble Coral Plerogyra

General information

In general, corals from the genus Plerogyra has a skeletal structure that is classified as flabello-meandroid. This means that their skeleton is not solid and not continuous. But instead, their skeletal structure has depressions or valleys. Their polyps can expand in a relatively large size that usually takes the form of grapes, tubes or irregular.

For the Green Bubble Coral Plerogyra, they are predominatly colored light blue with a green undertone on the side. This are the water parameters for cultivating Green Bubble Coral Plerogyra:

  • Calcium: 420 – 440 ppm
  • Alkalinity: 2.86 – 3.93 MEQ/L (8 – 11 dKH)
  • Phosphates: 0
  • Magnesium: 1260 – 1350
  • Strontium: 8 -10
  • Temperature: 75° – 80° F (24° – 27° C)
  • Salinity / Specific Gravity: 1.023 – 1.025
  • pH: 8.1 – 8.4

Diet & nutrition

The Green Bubble Coral Plerogyra get its primary nutrition from the symbiotic zooxanthellae living within its tissues. However, we still do recommend you do supplemental feeding by adding mysis and brine shrimp.

Determining sex

A mature tank is highly recommended in propagating Green Bubble Coral Plerogyra. They need to be set at the middle or bottom portion of the tank.

Breeding & spawning

Green Bubble Coral Plerogyra requires moderate lighting and moderate waterflow.

Origination

The Green Bubble Coral Plerogyra can be found in the waters of the Indo-Pacific Ocean. They are considered as a threatened species listed under Appendix II of the CITES List, which means that their international trade is monitored.

Cautions

The Green Bubble Coral Plerogyra has a semi-aggressive behaviour. With this, proper spacing in relation to other coral specimens is recommended.

Acclimation process

Since Green Bubble Coral Plerogyra is a marine species, salinity must be entirely maintained at 1.023 to 1.025 specific gravity.
