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 Yellow Line Shrimp

General information

The Yellow Line Shrimp is a relative newcomer to the hobby, making it a showcase species ideally suited for nano-reef aquariums. Nearly transparent as a defense, the Yellow Line Shrimp's body features scattered red and yellow spots, with a bright yellow line extending from the anterior end of its tail, where it splits into two stripes. In its natural environment, the Yellow Line Shrimp lives in groups in small caves and crevices on the reef in locations called cleaning stations. They use a side-to-side rocking dance to advertise the cleaning station to approaching client fish in the water column. Yellow Line Shrimp are reported to even climb inside gill cavities of welcoming fish to eat any parasites found there. It is not documented whether this shrimp's symbiotic relationship with client fish has successfully been reproduced in the home aquarium. Provide the Yellow Line Shrimp with plenty of hiding nooks and caves within the live rock, and avoid stocking with carnivorous fish that may consider the Yellow Line Shrimp a tempting meal.
