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 Lemon Damsel
General information
The Lemon Damsel is a small, bright yellow damsel with blue lines on the head and fins. Its appearance might get confused with the P.amboinensis, who has less bright color with a larger spot at the pectoral fin, unlike the Lemon Damsel. It inhibits branching corals and hides over the branches when frightened. With its stunning yellow color, the Lemon Damsel adds a splash of yellow color into the aquarium. As it grows, its color fades away and become more aggressive. Generally, the Lemon Damsel prefers to be solitary and mostly found feeding on the zooplanktons present in the tank. Damsel is a hardy fish, which can tolerate a wide range of water conditions and that makes it a very good choice for a beginner aquarist. The Lemon Damsel is a bit territorial and should be added last to the community tank so that it gets along well with other tank inhabitants.
