When choosing aquarium equipment, it’s important to consider the type of fish you have, the size of your tank, and your budget. Some basic equipment you’ll need includes a filter, heater, and lighting. The filter helps keep the water clean by removing debris and waste, while the heater maintains a consistent temperature for your fish. Lighting is important for plants and can enhance the beauty of your tank. Other optional equipment includes an air pump, substrate, and decorations. Research the specific needs of your fish and consult with a knowledgeable salesperson or aquarium professional before making your purchases.

Types of Aquarium Filters: Undergravel Filters
An undergravel filter is a cost-effective and reliable option that offers excellent results.

Biological aquarium filters, such as undergravel filters, have a different design and work differently than other filters.
The bacteria required for biological filtration, Nitrosomonas and Nitrobacter, can be found on almost any surface in a tank. However, due to limited surface area, these bacteria may not be able to process all the ammonia produced in a typical aquarium.
A biological filter solves this problem by enhancing the natural nitrogen cycle. It does so by increasing the surface area available to the nitrifying bacteria and creating a constant flow of aquarium water over the colonized area.
The most popular type of biological filter is the undergravel filter, which is cost-effective and reliable.
Undergravel filters consist of a plastic plate that covers the bottom of the aquarium and has small holes or slots. Aquarium gravel is placed on top of the plate, and lift tubes are located at each back corner of the plate, extending from the plate to the top of the tank.
The lift tube draws water from under the plate and pulls water down through the gravel, where the nitrifying bacteria use the dissolved oxygen in the water to metabolize ammonia and nitrite. The gravel provides a large surface area for the bacteria to colonize, and the steady water movement ensures that enough oxygen is available to support the colonies.
In addition to serving as a biological filter, undergravel filters also act as a mechanical filter by trapping solid particles that pass into the gravel bed. However, this can reduce the flow of oxygenated water past the bacteria and impair the biological filtration over time.
To solve this problem, a separate mechanical filter can be used to remove particles before they become buried in the gravel bed, and the gravel should be cleaned during water changes.
Undergravel filters do not function as chemical filters, although some may have small cartridges of activated carbon at the top of each lift tube. However, these cartridges do not last long and can significantly reduce water flow through the filter.
Next, we will discuss sponge filters, the last type of aquarium filter.

FAQ
1. What essential equipment do I need for an aquarium?
When setting up an aquarium, there are some essential pieces of equipment you will need. These include a filter, heater, thermometer, lighting, and substrate. The filter helps keep the water clean by removing waste and debris. The heater ensures that the water temperature stays consistent, which is crucial for the health of your fish. The thermometer helps you monitor the water temperature. Lighting is necessary for plants and fish that require it, and substrate is the material you use to cover the bottom of the aquarium.
2. How do I choose the right size aquarium?
When choosing an aquarium, consider the size of the fish you want to keep. A general rule of thumb is to have one gallon of water per inch of fish. So, if you want to keep a 10-inch fish, you will need a 10-gallon aquarium. However, keep in mind that some fish require more swimming space than others, so research the specific needs of the fish you want to keep.
3. What type of filter should I use?
There are several types of filters available for aquariums, including hang-on-back filters, canister filters, and sponge filters. The type of filter you choose will depend on the size of your aquarium, the number of fish you have, and the type of fish you have. Hang-on-back filters are suitable for smaller aquariums, while canister filters are better for larger aquariums and can handle more fish. Sponge filters are best for breeding tanks or tanks with fry.
4. How do I choose the right heater?
The size of the heater you need will depend on the size of your aquarium. A general rule of thumb is to have 5 watts of heating power per gallon of water. For example, if you have a 20-gallon aquarium, you will need a heater with at least 100 watts of heating power. Additionally, choose a heater with a thermostat to ensure that the water stays at the correct temperature.
5. Do I need a substrate in my aquarium?
While substrate is not essential, it is recommended for most aquariums. Substrate provides a natural environment for fish and plants, helps with biological filtration, and can enhance the aesthetic of the aquarium. Choose a substrate that is appropriate for the type of fish and plants you have, as some require specific types of substrate.
6. What type of lighting should I use?
The type of lighting you need will depend on the fish and plants you have in your aquarium. Some fish and plants require high-intensity lighting, while others only need low lighting. Additionally, consider the color temperature of the lighting. A warmer color temperature will enhance the colors of your fish, while a cooler color temperature will promote plant growth.
7. How often should I clean my aquarium equipment?
The frequency of cleaning your aquarium equipment will depend on the size of your aquarium, the number of fish you have, and the type of filter you are using. In general, it is recommended to clean the filter once a month and replace the filter media every three to six months. Additionally, it is essential to perform regular water changes to keep the water clean and healthy for your fish.
8. How do I maintain the equipment in my aquarium?
Regular maintenance of your aquarium equipment is crucial for the health of your fish. This includes cleaning the filter, checking the heater and thermometer, and replacing any equipment that is not functioning correctly. Additionally, perform regular water tests to ensure that the water parameters are within the correct range for your fish and plants.
