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 Margarita Snail

General information

The Margarita Snail is one of the most sought after home reef inhabitants. This is because they can consume large amounts of algae, including nuisance hair varieties. Plus, unlike some snails, Margarites pupillus is non-venomous and peaceful towards corals, invertebrates, and other tankmates. The Margarita Snail has a brown body and smooth, turban-shaped shell and may grow up to 1" as an adult.
The Margarita Snail does well in the home aquarium provided it is well established and has an ample algae source for the Margarita Snail to feed upon. For best care, they should be kept at cooler water temperatures with other peaceful tankmates. However, most Margarita Snails can adjust to an aquarium with a water temperature as high as 78 degrees Fahrenheit. Like other invertebrates, the Margarita Snail is sensitive to high nitrate levels and copper-based medications. Also, it should be acclimated to new aquariums using the drip acclimation method. The Margarita Snail is sensitive to even small changes in water parameters including pH, temperature, and alkalinity. To promote shell growth, supplement calcium levels in your aquarium.
