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 Green Clown Goby
General information
The Green Clown Goby is common within the reefs of the Indo-Pacific found usually among soft and hard coral colonies. They are a small stocky shaped fish with a very large head for their size. There are many different color variations, and this species is a yellow to greenish-tan color with orange vertical stripes on its head. They are a peaceful fish that makes a wonderful addition to a reef aquarium containing colonies of polyp corals, as they enjoy swimming and hiding amongst the polyps. However, they may nip at the polyps of SPS corals. It will rarely become aggressive towards other fish but will fight with its own kind in smaller tanks. Therefore, it is best if it is kept with other docile species. It is common for clown gobies to spawn in an aquarium. Caution should be exercised if the aquarium contains Acropora sp. or similar SPS corals. They will lay their eggs on the underside of the coral’s branch, which will cause tissue recession in that area of the coral. However, under good conditions, the coral will regenerate the lost tissue.
Cautions
Gobies are considered jumpers make sure your aquarium has a tight-fitting canopy or screen cover to prevent the Gobie from jumping out of your aquarium. Gobies have been known to jump through the smallest of holes in a canopy.
