petnet has learned that if you want to raise tropical coral reef fish and invertebrates, it goes without saying that the temperature of the aquarium should be kept at the temperature of natural tropical seawater In the temperature range, that is, between 25-27°C, corals will grow best in an environment within this temperature range. When the temperature falls below 20°C, or exceeds 30°C, calcium corals stop synthesizing calcium (destruction immediately after formation). Once the temperature exceeds the range of 15-32°C, most corals die. Therefore, the heating of the seawater aquarium must be very careful, otherwise it may cause accidents, because of the high conductivity of seawater, the current in the heater may be almost completely conducted into the water, which will cause serious damage to every corner of the aquarium. Influence.

Appropriate Lighting

Appropriate Lighting refers to single cells that ensure symbiosis with invertebrates The light where the zooxanthellae continue to survive and reproduce. The light in the natural coral reef ecosystem is quite strong, so it is difficult to imitate. However, the use of metal halide lamps, also known as HQI spotlights, can bring the water surface illumination of the aquarium to an intensity of 80,000 lux, which is sufficient for the metabolism of unicellular zooxanthellae in invertebrates 60 cm below the water surface of the aquarium, and in this way Under the sunlight, the coral's calcium can be synthesized smoothly, so the coral can continue to grow.

Of course, some organisms will avoid the strong light, It is therefore necessary to create a shaded area in the aquarium, for example between two lights.

Safe and stable water

The main concern is the stable salt composition. A saltwater aquarium containing invertebrates should preferably maintain a salt content between 1.0221.023 specific gravity. Special note: the measurement is temperature necessary It is carried out under 25oC. The most advanced salt content measurement equipment is a conductivity meter for measuring seawater (conductmeter standardizes that the conductivity value of seawater should be between 4751ms/cm and safe water quality. The measurement should also include suitable carbon. Acid hardness (carbonhard should be maintained between 7o9odH. In addition, other conditions that help maintain water quality, such as: iron content (ironcontent must be 0.1mg/l) and nitrate (nitrat and carbon dioxide (carbondioxid, etc.) Attention should be paid.

Maintaining invertebrate function

Unicellular zooxanthellae are important for invertebrates The metabolism of animals is very important. With its help, the nutrient content in the aquarium can be kept within a certain range. For example, the iron content in seawater is a decisive factor. The maintenance of 0.1mg/l function also includes the use of carbon dioxide to maintain a constant pH value (pH range, and unicellular zooxanthellae can also absorb large amounts of carbon dioxide, which in turn breaks down nitrates into amino acids and other substances. These symbiotic algae The synthesized products include sugars, glycerol, and amino acids, which can be taken up by the host (living coral) or as part of its own tissue system. These single-celled zooxanthellae also occasionally take up phosphates from seawater and Nitrogenous metabolites of symbiotic coral hosts.
