Aquarium Basics

Before you start creating your aquarium, it’s important to understand some basic aquarium terms. Here are some of the most common terms that you should know:

Cycling

Cycling refers to the process of establishing a biological balance in your aquarium. This involves cultivating beneficial bacteria that convert harmful ammonia, produced from fish waste, into safer substances like nitrate. This process is essential before adding fish to your new aquarium.

pH

pH is a measure of the acidity or alkalinity of your aquarium water. The pH scale ranges from 0 to 14, with 7 being neutral. A pH level of 7.0 is ideal for most freshwater fish. However, some fish species may require a slightly different pH level.

Nitrogen Cycle

The nitrogen cycle is a natural process that occurs in your aquarium. It involves the conversion of ammonia to nitrite and then to nitrate. Ammonia is produced by fish waste, uneaten food, and decaying plants. Nitrite is also toxic to fish, but it is less harmful than ammonia. Nitrate is the least harmful of the three nitrogen compounds and can be removed through regular water changes.

Filtration

Filtration is the process of removing waste and debris from your aquarium water. There are three types of filtration: mechanical, chemical, and biological. Mechanical filtration removes physical debris from the water, chemical filtration removes impurities, and biological filtration removes harmful nitrogen compounds.

Water Change

A water change involves removing a portion of your aquarium water and replacing it with fresh water. This process helps to remove excess nutrients, waste, and harmful compounds from your aquarium water. Regular water changes are essential to maintaining a healthy aquarium environment.

3. What Do I Need For a Fish Tank?

There are a few basic things you need for your new aquarium to get started:
