Water parameters

76-80 F
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 Going Rainbow Acan
General information
Going Rainbow Acan has a brightly colored corallite which is similar to the colors of a rainbow. But we remind you that the similarities are only for the color composition and not the pattern itself.
This is the ideal range of water parameters for raising Going Rainbow Acan in captivity:
- Calcium: 400 – 450 ppm
- Alkalinity: 3.2 – 4.8 MEQ/L
- Phosphates: 0
- Magnesium: 1200 – 1350
- Strontium: 8 – 10
- Temperature: 76° – 83° F (24° – 28° C)
- Salinity / Specific Gravity: 1.023 – 1.025
Diet & nutrition
In the wild, Going Rainbow Acan has developed a symbiotic feeding relationship with a marine algae called zooxanthellae. But in captivity, you have to feed them with nanoplankton or dissolved organics.
Determining sex
A mature tank is highly recommended in propagating Going Rainbow Acan. Thriving them with fish is recommended as fish excretes nitrogen that can sustain the coral's growth.
Breeding & spawning
Going Rainbow Acan does not need high flow rate and intense light. Giving them moderate lighting allows the Going Rainbow Acan to spread their polyps thereby allowing them to feed. Too much light will cause the polyps to be retracted.
Cautions
Except for their own kind, Going Rainbow Acan is aggressive towards other species. During night, they extend their tentacles and sting nearby corals. It is recommended to observe proper spacing between corals. Further, they have the tendency to be overpowered with soft corals and will die especially if soft corals outnumbers them.
Acclimation process
Going Rainbow Acan are purely marine. So therefore, salinity must be maintained thoroughly at 1.023 to 1.025 specific gravity.
