  • Tap water can contain pollutants that can damage aquatic life, so using purified water helps prevent this.
  • Filtration systems are important to keep the tank clean and remove metals, chemicals, bacteria, and microorganisms.
  • Regular testing and monitoring of water conditions are necessary to maintain ideal salinity levels, pH balance, and overall water quality.

What Is Purified Water

Purified water is water that’s been treated to remove contaminants. It typically comes from tap water that has gone through a filtration process or reverse osmosis. Purified water can also come in the form of distilled or deionized water.

This type of water is free of chemicals, minerals, and other impurities, and is considered safe for consumption. Despite its purity, purified water isn’t ideal for saltwater aquariums due to its lack of essential nutrients and minerals needed by aquatic life.

What Is Saltwater Aquarium

Saltwater aquariums are tanks filled with sea water, containing coral and fish. These specialized tanks require special care for healthy inhabitants.

Regular maintenance, such as water changes and chemical checks, ensure the well-being of the corals and fish. Corals need specific lighting and temperature levels to survive while many fish require a certain level of salt in their environment.

Quality purified water is essential for keeping these elements balanced; otherwise, it could be detrimental to the health of your aquatic life.
