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 Aussie Ultra Scoly

General information

In general, corals coming from the genus Scolymia are round solitary corals that has a single mouth located at the center. Their coloration usually has an alternating radial bands with a cup, saucer, flat or dome shaped variations.

As for the Aussie Ultra Scoly, they are predominantly colored red and violet. This are the water parameters for cultivating Aussie Ultra Scoly:

  • 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 primary nourishment of the Aussie Ultra Scoly is provided by the symbiotic zooxanthllae living within its tissues. But on top of this, we recommend you still do supplemental feeding by adding mysis or brine shrimp.

Determining sex

A mature tank is highly recommended in propagating Aussie Ultra Scoly. They need to be set at the bottom level of the tank.

Breeding & spawning

The Aussie Ultra Scoly requires moderate lighting and low water flow.

Origination

The Aussie Ultra Scoly can be found in the waters of the Indo-Pacific Ocean, particularly in Japan, Malaysia, Polynesia and Australia.

Cautions

You have nothing to worry about Aussie Ultra Scoly. They have a peaceful behaviour and do not attack even if there is a nearby coral.

Acclimation process

Aussie Ultra Scoly are a marine species. Therefore, salinity must be entirely maintained at 1.023 to 1.025 specific gravity.
