Will the kh high coral in the trough die?

If the kh of the trough is high, the coral will not die, but it will do harm to the coral.

The cause of coral death:

1, the water quality is too poor, and NO3 exceeds the standard.

2, the illumination time is too long, resulting in a large change in water temperature.

3. Feed a large number of bump shrimps and the remaining bump shrimps that have not been eaten.

4. Accidentally injuring corals in the process of handling corals, resulting in local necrosis and development to complete death.

Coral growth adaptation conditions:

Specific gravity of seawater: about 1.025, pH: about 7.9-8.4, KH: about 7- 12 DKH, NO3:
