Water parameters

Temp 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 Hydrogen

Measuring the acidity or alkalinity of water on a 0–14 scale, where 7 is neutral, 7 is alkaline.

NO3 1-20 ppm Nitrate

While 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 Nitrite

It is a highly toxic, intermediate compound in the nitrogen cycle produced from broken-down ammonia

PO4 0.01 - 0.1 ppm Phosphate

It is essential for plant development but must be managed, as excess levels trigger nuisance algae blooms and inhibit coral calcification.

NH3 <0.1 ppm Ammonia

It is the primary killer of aquarium fish, causing gill damage, stress, and death

Ca 380 - 450 ppm Calcium

Supporting the growth, skeletal structure, and shell formation of corals, mollusks, crustaceans, and coralline algae

KH 8 - 12 dKH Alkalinity

It acts as a shield, neutralizing acids to prevent dangerous pH "crashes" that can harm fish, corals, and plants.

Mg 1200 - 1400 ppm Magnesium

It 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 Salinity

Essential for maintaining stable, natural water parameters, proper osmoregulation, and stress-free environments for marine fish and corals

ORP 250 - 400 mV Oxidation-Reduction Potential

A higher positive mV indicates clean, oxygen-rich water with high water quality, while low readings indicate high pollution.

About Sebae Anemone

General information

Heteractis malu it was previously named Radianthus keukenthali. Heteractis malu is usually light tan to brown in color, and may have purple tips on its tentacles. Acclimation to aquarium life can be very difficult for this species and its care should only be attempted by the most experienced aquarists. In the aquarium, it requires strong lighting, porous live rock, and a variety of sandy and rocky locations from which it can choose to live. The addition of a Clownfish, such as the Blue Striped Clown, Amphiprion chrysopterus, will immediately help with its acclimatization and improve its chances of survival. When healthy, it will become very sticky. If it grasps onto something (or someone), it will be very difficult to convince it to let go without damaging it.

Hosting
The Heteractis Malu anemone has been known to have a symbiotic relationship with A. Akallapisos (Skunk Clownfish), A. Clarkii (Clark's Clownfish), A. Melanopus (Red and Black Clownfish), A. Ocellaris (Ocellaris Clownfish), A. Percula (Percula Clownfish), A. Perideraion (Pink Skunk Clownfish), A. Akallopisos (Skunk Clownfish).
