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 Lime Time Astreapora

General information

In general, Astrepora corals have colonies that are rounded or dome-shaped. Their corallites are distinct, separated and uneven while their exoskeleton are porous.

For the Lime Time Astreapora, they are predominatly colored green with neon green circles at the tips. This are the water parameters for cultivating Lime Time Astreapora:

  • Calcium: 400 – 450 ppm
  • Alkalinity: 3.2 – 4.5 MEQ/L
  • Phosphates: 0
  • Magnesium: 1350 – 1500
  • Strontium: 10
  • Temperature: 72° – 78° F (22° – 26° C)
  • Salinity / Specific Gravity: 1.024 – 1.025

Diet & nutrition

The main noursihment of Lime Time Astreapora comes from the photosynthetic activity of the symbiotic zooxanthellae living within their tissues. However, we still recommend the supplemental feeding of mysis, brine shrimp and other micro foods.

Determining sex

A mature tank is highly recommended in propagating Lime Time Astreapora. They should be set in the middle or bottom portion of the tank.

Breeding & spawning

The Lime Time Astreapora requires moderate water flow and low lighting. This is the reason why you should set them at the middle or bottom of the tank.

Origination

Lime Time Astreapora are found in the waters of the Indo-Pacific Ocean.

Cautions

The Lime Time Astreapora is susceptible to polychaete worm infestation. The worms will penetrate to its porous exoskeleton thereby weakening its overall calcareous structure.

Acclimation process

Lime Time Astreapora are purely marine. Therefore, salinity must be maintained thoroughly at 1.023 to 1.025 specific gravity.
