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 Immaculatus Puffer

General information

The Immaculatus Puffer captures the essence of the specialized nature of puffers. Classic and elegant in design, the Immaculatus Puffer has a large, pillowy body that is predominately milky white with neutral overtones of varying shades of tan and brown. Unexpected bursts of yellow highlight the large paddle-like caudal fin, mouth and eyes of the Immaculatus Puffer. This simple yet bold color combination gives the Immaculatus Puffer a sophisticated and exotic presence. In this sense, one may argue that the Immaculatus Puffer shares a striking resemblance to Cockatoos. It is reputed that the Immaculatus Puffer can alter from its blemish-free appearance to a blotchy, mottled appearance depending on its mood and circumstance. The Immaculatus Puffer is an exceptional fish sure to make an endearing addition for puffer enthusiasts or anyone wanting personality in their larger, fish-only or fish-only-with-live-rock marine aquarium. Members of genus Arothron, including the Immaculatus Puffer exemplify the typical puffer design. Though lacking pelvic fins and a hydrodynamic body shape, puffers are extremely maneuverable and are tenacious and capable predators. Like many Fat Puffers, the Immaculatus Puffer displays an unusual degree of intelligence and personality and appear to quickly recognize their owners. In the wild, the Immaculatus Puffer inhabits a wide range of habitats including mangrove swamps, seagrass beds, and reef flats. The ideal setup should be a large established aquarium with good filtration and a protein skimmer. Aquascape liberally with live rock and other materials to create an environment rich with nooks and crannies, caves and overhangs while preserving easy access to large open areas. House with fish of similar size and temperament and be aware that the Immaculatus Puffer will eat invertebrates found in the aquarium using its fused beak-like teeth to crush open its prey.
