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 Purply Goni

General information

In general, corals coming from the genus Goniopora have numerous corallites that are walled invidually. Each corallite has a polyp that is usually exposed and extended. Their polyps are usually long, has a daisy-like tips each having 24 tentacles and sways like a flower tube.

As for the Purply Goniopora, they are predominantly colored purple with white tips at the polyps. This are the water parameters in cultivating Purply Goniopora:

  • Calcium: 400 – 450 ppm
  • Alkalinity: 3.2 – 4.8 MEQ/L
  • Phosphates: 0
  • Magnesium: 1200 – 1350
  • Strontium: 8 – 10
  • Temperature: 76° – 83° F (24° – 28° C)
  • Salinity / Specific Gravity: 1.023 – 1.025

Diet & nutrition

The Purply Goniopora get its primary nutrition from the symbiotic zooxanthellae living within its tissue. But on top of this, we still recommend you do supplemental feeding by adding mysis and brine shrimp. Further, the additional of dissolved organics is highly recommended.

Determining sex

A mature tank is highly recommended in propagating Purply Goniopora. They should be set on the middle or bottom part of the tank.

Breeding & spawning

The Purply Goniopora requires moderate to strong lighting and moderate waterflow.

Diseases

The Purply Goniopora is susceptible to mortality caused by nutritional deficiencies. With this, the addition of supplemental nutrition and nutrients is highly recommended.

Origination

The Purply Goniopora can be found in the waters of the Indo-Pacific Ocean, particularly in the Philippines and Indonesia. They are listed as a vulnerable species under Appedix II of the CITES list.

Cautions

The Purply Goniopora has an aggressive behaviour and may require adequate spacing in relation to other corals in the tank.

Acclimation process

The Purply Goniopora is purely marine. So, therefore, salinity must be maintained thoroughly at 1.023 to 1.025 specific gravity.
