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 Snapping Shrimp

General information

The Snapping Shrimp is found in a variety of colors and sizes. Snapping Shrimp are not easily sexed, but the males of many species are thought to have a larger pincher. The sound it makes comes from an appendage on the pincher which moves when the pincher is opened or closed and water is ejected. The Snapping Shrimp can be easily confused with Mantis Shrimp if judged by sound only. Unlike the Mantis Shrimp, it is not harmful and will not pose any threat in the tank, with the possible exception of smaller shrimp. The name Symbiotic Shrimp comes from the equally beneficial relationship the Snapping Shrimp has with gobies (e.g.;Amblyeleotris or Stonogobiops). The goby, with better eyesight, warns the shrimp of predators. The shrimp share its food with the goby. Depending upon the species, Snapping Shrimp may also have symbiotic relationships with sponges, corals, or anemones. It is beneficial to the tank as it churns the sand. It thrives in environments with sand, rock caves, and dim light. If in pairs, one will often stand guard at the burrow while the other is inside. The Snapping Shrimp is intolerant of copper or high nitrate levels, but needs a correct level of iodine in the water to promote proper molting.
