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 Manjano Anemone
General information
The Majano Anemone is one of the top pest anemones in saltwater and reef tanks. They have strong stings and are aggressive to other corals and fish in your tank. They use venomous cells, nematocysts found in their tentacles, to sting corals and fish. They can be a challenge to get rid of and have been known to take over an aquarium quickly reproducing while stinging and killing other tank mates.
Like Aiptasia, the Majano Anemone is a hitchhiker that attaches to live rock or frag plugs. The best way to avoid them in your main display is to quarantine all new purchases and observe them in the quarantine system to prevent them from getting into your display.
Natural predators for Majano Anemone are Peppermint shrimp which can be added to control them. Keep in mind that they may not touch them and instead go after your corals instead or once the Majano’s are gone go, they may start to attack other corals.
