30 Gallon Fish Tank Reviews

SeaClear Acrylic Aquarium

This tank is made of acrylic instead of glass, meaning it is much stronger and safer. With acrylic tanks, the material allows a much clearer view of your fish rather than glass. It is safe for both freshwater and saltwater fish.

Acrylic tanks weigh about half as much as glass tanks, so it will be less of a hassle to move it within your home. Also, you won’t need to worry about the supportive base underneath it since the tank will not be as heavy as a glass one would be.

Since it is made of acrylic material, it is less prone to cracking or breakage. This tank prevents the material warping once it is filled with water, but some bowing overtime was reported.

This tank comes with a light fixture to illuminate the tank, making your fish much easier to see. It also comes with a reflector.

Pros:

  • Made from acrylic material
  • A clearer view of the fish
  • Perfect for saltwater and freshwater fish

Features of 30-Gallon Fish Tank

If you are on the hunt for a 30-gallon fish tank, it is important that you know the different factors that vary between each product. This will ensure that you find the perfect choice that meets all of your expectations and priorities.

  • Material: Fish tanks are most commonly made of either glass or acrylic. Glass usually will not have discoloration over time and it is almost scratch-resistant, while acrylic aquariums are less heavy, more sturdy, and they have better visual clarity. In general, fish tank owners would rather an acrylic tank as the pros far outweigh the pros of a glass tank.
  • Shape: Most fish tanks come in a rectangular, box-shaped tank. However, some other shapes include cubes, cylinders, and hexagons. The great thing about the rectangular, box-shaped tank is that it is compatible with other aquarium features such as filters, UV sterilizers, other types of lights, and decorations. The great thing about the other shaped tanks is that they add a visual edge that looks aesthetically pleasing to the eye compared to a normal shaped tank.
  • Filters: Some tanks come with built-in filters and some do not. Usually built-in filters come with smaller sized tanks, but there are some that occasionally come with 30-gallon sized tanks. The benefit of a built-in filter is that you won’t need to buy one separately. However, it is important to note that the filters that come pre-installed with the tank sometimes are not the best quality. If having an excellent filter is your top priority, purchasing a filter on the side is your best option.

How to Maintain a 30-Gallon Fish Tank

The best thing to make sure you are maintaining a healthy environment in your tank is having a good filtration system. A good filter is going to cleanse your water from any excess food and waste and convert harmful bacteria to beneficial bacteria.

It is important that you do weekly or biweekly water changes in order to maintain the water. This will also help to make the water appear less water. You should be cleaning approximately 20% of the water every week or two, but some fish owners prefer to change out a larger amount.

A feature that is great for maintaining your fish tank is purchasing a UV sterilizer which goes the extra mile further than only a filter. The UV light penetrates any toxins or viruses. This ensures a cleaner tank and longevity of your aquatic life.

The number of fish also affects how you maintain your fish tank. The larger the amount of fish, the more you will need to clean the tank. This is due to the fact that more fish produce more waste to infect the tank. Another thing to consider is the type of fish you have. This is because different species of fish produce different amounts of waste. For example, goldfish tend to produce more waste and bettas tend to produce less waste.

Another important factor in maintaining your tank is by making sure it is at the proper temperature. This can be accomplished through having an aquarium thermometer. This is going to monitor your water temperature, and it will alert you if your water is at a dangerous temperature.

Benefits of Having a 30-Gallon Fish Tank

A 30-gallon fish tank is the perfect size for a beginner. This is due to the fact that it isn’t too big or too small. It is a great substitute for a 50-gallon aquarium. It requires less space and maintenance than a larger aquarium, but you can still have the freedom and creativity to hold a diverse selection of plants and aquatic life.

Another benefit of choosing a 30-gallon sized fish tank is that a lot of the tanks will come in kits. This is because smaller sized tanks often come in kits. These kits often include filters, heaters, lamps, decorations, and more.

A great thing about 30-gallon fish tanks is that they are able to serve many types of applications including freshwater, saltwater, and planted aquariums.
