Will an Aquarium Increase Humidity in Your Home?


Fishkeeping in an aquarium is a great hobby. Not only do you get to learn about how to care for your fish, the end result is a calming and soothing aquarium full of colorful fish. But is there a downside to keeping a tank of water in your house? Will an aquarium increase humidity in your home or apartment?

A fish aquarium will increase the humidity in your home. Whether or not it becomes a problem depends on the size and number of fish tanks. If humidity is a problem, it can be reduced by using tank covers, fans and dehumidifiers.

Chances are, if you have one aquarium in your home, it won’t be a problem. But let’s take a closer look.

How to Determine if There is Excess Humidity in Your Home

Many homeowners install open fish tanks, which may be just fine with less than 15 aquariums, each carrying ten gallons. Any size beyond this automatically leads to humidity problems. You can determine if there is excess humidity in your home if you notice this happening:

  • Condensation appears on the inside of your windows
  • Mold and mildew is visible
  • Musty smell
  • Allergies become more intense

Dealing with the Humidity Problem

After determining that your aquarium is causing excess humidity conditions, you must immediately take the right measures to prevent further damage. They include:

1. Cover the Fish Tanks

The first step to control aquarium-related humidity is purchasing those that have tight covers. The lids help in preventing evaporation of water and minimizes the moisture in the house. The best tops should be made from thermal twin-wall 6-8mm of polycarbonate sheeting.

2. Install Hydroponic Fan

Consider installing a Humidity Control 10″ Hydroponic Fan in the room where the aquarium is located. By using this fan, along with having a lid on the aquarium, you can reduce the humidity by 30-45%. Thus, you’ll be able to solve the mold problem and reduce the humidity level in the room.

3. Dehumidifiers

This equipment is mostly placed in areas where your aquariums are located. Dehumidifiers help remove excess moisture from the air and work most efficiently when kept away from walls or any other object that obstructs the airflow. You may also decide to install large scale dehumidifying systems for the entire home. They function best when you completely seal off the fish tank room or after closing all the doors and windows of your house.

4. Proper Ventilation

There are several ways you can ensure your home is adequately ventilated. When you notice moisture present in the house, consider turning on the ceiling fans or whole house fan. If your house lacks exhaust fans, consider installing extra fans to minimize the humidity.

5. Weatherstripping

Applying weatherstripping around your doors and windows, especially in the aquarium room, helps to create an airtight seal. This way, no cold or warm air escapes the room and prevents excess humidity from getting inside. Weatherstripping is necessary when installing your fish tanks in warm climates.

6. Insulation

According to Energy.gov, “Proper insulation helps control humidity levels in your home. This process helps retain the heat and prevent other foreign particles from entering the room. Insulation prevents warm air from escaping and getting in different gaps within the walls of your home.”

Apart from these six ways to solve the high humidity problem, consider regularly cleaning your AC ducts and air filters, and setting your AC/HVAC unit to AUTO rather than ON. To understand more about aquariums increasing the humidity in your home, watch this video from Prime Time Aquatics.

Do Aquariums Increase Humidity in Your Home?

If you are a homeowner, the idea of introducing an aquarium or installing a fish tank in your home can be exciting. Most people will install aquariums in their basements or somewhere visible within the house.

While these aquariums add beauty and make your home livelier, they also increase humidity in the home. According to Oregon State University, tropical fish tanks, and other indoor house plants can add a significant amount of moisture to the air.

Problems from Excess Humidity

Uncontrolled and excessive humidity from the aquariums can cause several problems, including:

1. Mold and Mildew: Most basements and crawl spaces lack proper ventilation and can easily trap humidity generated from the aquariums. The humidity and moisture then combine to form mildew. Additionally, wooden parts can absorb the moisture and cause mold to grow. Formation of mold and mildew weakens the structure, which may eventually collapse and cause injuries and damages.

2. Health Hazards: The production of mold and mildew can cause health problems for you and your family. Mold and mildew produce spores that are airborne and can travel through the air ducts and pollute the air in your home. According to WebMD, mold causes a runny nose, skin rashes, and allergies, especially in young children, the elderly, and people with compromised immune systems.

3. Mechanical Problems: Humidity from aquariums can also settle and condense on water pipes, mechanical objects, HVAC systems, and other surfaces within your home. Over time, they can cause rusting and failure to mechanical components. Failed equipment can be costly to repair and maintain.

4. Damage to Floors and Walls: High humidity and moisture levels can cause the formation of mold and mildew on your home carpeting. When this happens, it can create a dank, musty odor which can be difficult to clean and remove completely. It may be necessary to replace the carpet, which will be expensive. An increase in moisture content causes air pockets to form on your walls, and this, in turn, destroys your paint, wallpaper, or drywall. When mold attacks the wood in your home, it creates dry rot which will require a professional to remove and replace.

5. Household Items: If the humidity is not controlled with your aquarium, food, clothing, furniture, and window coverings can also be destroyed by the mold and mildew.

Conclusion

Installing an aquarium in your home is a great idea. However, you must also understand that it may cause excess humidity in your home. We hope this post gives you an insight on how to keep the humidity from causing problems with your house and your health by utilizing the tips we have shared.
