Saltwater Aquarium Glossary


Salinity refers to the measure of salt content in water. In the context of a saltwater aquarium, salinity is an important factor to monitor and maintain, as it affects the health and well-being of the marine inhabitants. The salinity level of a saltwater aquarium is typically measured in parts per thousand (ppt), and a range of 32 to 35 ppt is considered ideal for most marine fish and invertebrates.

Protein Skimmer:

A protein skimmer is a device used in saltwater aquariums to remove organic waste and debris from the water. It works by creating a column of bubbles that attract and collect waste particles, which are then removed from the aquarium via a collection cup. Protein skimmers are an important component of a saltwater aquarium filtration system, as they help to maintain water quality and reduce the risk of harmful toxins and bacteria.

Live Rock:

Live rock is a porous rock formation that is used in saltwater aquariums as both a decorative element and a biological filter. It is typically made up of pieces of dead coral and other marine organisms that have become encrusted with living organisms such as bacteria, algae, and invertebrates. Live rock provides a habitat for beneficial bacteria that help to break down waste and maintain water quality, as well as a food source and hiding place for many marine inhabitants.
