Managing a reef tank salinity level is one of the most fundamental skills you will learn as a saltwater hobbyist.
Our salinity stability guide shows how to measure, maintain, and correct reef tank salinity without stressing corals or fish.
Hi! Welcome to reef 2 reef! :) I wanted to clarify that if you have an anemone and a coral in the tank, you DO have livestock. Inverts, corals and fish all are considered livestock. As far as salinity, if you have 33 ppt. that equals 1.0245 specific gravity. 35 ppt. equals 1.026 specific gravity Its fine to keep a reef tank at 1.024 to 1.026.
Maintaining proper reef tank parameters is essential to the health and well-being of fish, coral, and invertebrates inside your aquarium. Fluctuations in a key aquarium parameter, such as temperature, salinity, pH, ammonia, or nitrate can result in some serious stress upon your tank inhabitants, algae blooms, and disease.
Parameter-by-Parameter Breakdown Salinity Salinity is the most foundational parameter in a reef tank. It determines the concentration of every dissolved ion and directly affects osmoregulation in every organism. A stable 35 ppt matches natural seawater and provides optimal conditions for corals, fish, and invertebrates. Measure with a calibrated refractometer. Swing-arm hydrometers lack the ...
