Temperature
Maintaining a stable and appropriate temperature is critical for the survival of aquatic life.
pH 7.8 - 8.4 potential of HydrogenMeasuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.
NO3 1-20 ppm NitrateWhile 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 NitriteIt is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia
PO4 0.01 - 0.1 ppm PhosphateIt is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.
NH3 <0.1 ppm AmmoniaIt is the primary killer of aquarium fish, causing gill damage, stress, and death
Ca 380 - 450 ppm CalciumSupporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae
KH 8 - 12 dKH AlkalinityIt acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.
Mg 1200 - 1400 ppm MagnesiumIt 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 SalinityEssential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals
ORP 250 - 400 mV Oxidation-Reduction PotentialA higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.
About Four Stripe Damselfish
General information
They are found in the Western Pacific, from Sumatra to Vanuatu and northwards to the Ryukyu Islands of Japan. This species can also be found Southwards, down to New Caledonia and Tonga. The Four Stripe Damselfish is a member of the Pomacentridae family. In appearance, they feature a total of four blacks bars along with three white bars and a white spot above its lip. The Black-Tailed Dascyllus usually grows up to a maximum size of 3 inches in length. This species also readily consumes finely chopped meaty foods. It is recommended to feed the Four Stripe Damselfish in small amounts several times a day. This species is usually aggressive in temperament, especially as they grow older. Hence, it is better when they are kept in a community tank with other aggressive fishes. However, the Black-Tailed Dascyllus do not harm any invertebrates or cause any kind of destruction in the tank.
