What is a good temperature for corals?

Reef-building corals cannot tolerate water temperatures below 64° Fahrenheit (18° Celsius). Many grow optimally in water temperatures between 73° and 84° Fahrenheit (23°–29°Celsius), but some can tolerate temperatures as high as 104° Fahrenheit (40° Celsius) for short periods.

Is coral farming profitable?

How long does it take for a coral to grow?

10,000 years

How do you know if coral is growing?

You should see some noticeable coral growth every week. A good test is to measure dKH and then a week later and without dosing, measure dKH again. If the dKH falls, this is a good sign that corals are growing as they need the carbonates to build their skeletal mass.

How do you attach coral to live rock?

The glue is what actually does most of the bonding.

  1. Trim your frag plug if necessary.
  2. Mix up a small ball of AquaMend putty.
  3. Apply the super glue gel to the frag or plug.

Corals are found across the world’s ocean, in both shallow and deep water, but reef-building corals are only found in shallow tropical and subtropical waters. This is because the algae found in their tissues need light for photosynthesis and they prefer water temperatures between 70-85°F (22-29°C).
