        How To Choose A Dehumidifier For A Fish Room?

        Many people have told me that keeping the aquarium closed reduces the humidity, but it depends on what kind of aquarium you have, what kind of fish you have, the number of fish tanks, the size of the room, and more. 

        In my case, I can’t keep the tank closed. I have more than one and it has brought me problems with mold! Definitely not healthy for anyone.

        Here are some guidelines to keep in mind when choosing a dehumidifier for a fish room.

        There are two types of dehumidifiers on the market compressor and desiccant.

        Compressor Dehumidifier: 

        Draws air from the space in question over a filter. The air is then moved to the cold coils, where it condenses, and then exits in the form of droplets. This type of dehumidifier is not recommended for very low temperatures.

        Desiccant Dehumidifier: 

        Uses hygroscopic substances, such as silica gel, to absorb moisture from the air. It has no compressors, is usually lighter and quieter. Its disadvantage is that it tends to consume more energy.

        Extraction Capacity: 

        This is the amount of water that the dehumidifier can extract in a given time, i.e. the number of liters per 24 hours.

        For example, generally, for a very humid room measuring 500 square feet or more, a device with at least 20 liters or 5 gallons of capacity is required.

        Discharge Options: 

        It is important to consider this if you do not want to be emptying the dehumidifier tank all the time. Make sure it can store as much water as possible so that the equipment is more autonomous.


        All the surfaces in square meters that the dehumidifier will cover.


        It is the humidity regulator; it can be manual or electronic. Some come with sensors to measure the humidity level of the space and modify its speed depending on the need. 


        This way you will take care of the compressor motor and extend its life. Generally, it can be programmed to achieve a relative humidity between 40% and 80%. 

        In this way, we can save energy by programming the cessation of activity below the threshold we have set.

        Power Consumption: 

        we all want cleaner air at a good price, so dehumidifiers are becoming more and more energy-efficient with automatic on/off options. 

        A standard dehumidifier operates at about 300 watts and the higher the capacity, the more it will consume.

        Sound Level: 

        a good fish room dehumidifier should go unnoticed.

        Decibels are used to measure the noise level of dehumidifiers. If the decibel number is 40 or less, it is considered to make little noise. Compact, low-capacity dehumidifiers are usually quieter, with levels around 35 decibels.

        Dehumidifier FAQ

        Will dehumidifiers affect a fish tank?

        No, dehumidifiers do not affect tanks negatively, but depending on various factors, they may evaporate a little more water, but it will not affect the water levels in the fish tank significantly. 

        A dehumidifier, on the other hand, will keep your fish room free of fungus and keep the air cleaner.

        Will a dehumidifier evaporate water?

        Yes, dehumidifiers generally evaporate the water in the tank by drawing moisture from the air, the higher the temperatures, the greater the evaporation.

        When dehumidifiers are running, they produce heat, which makes the air in the room even drier and induces more evaporation. According to experts, humidity levels in a space should be between 30% and 50%1. 

        When levels are maintained in this range, condensation is reduced and the spread of mold and mildew is prevented.

        Although this may cause additional evaporation in the aquarium, it will help maintain a proper temperature in the environment.

        Having a humidity meter for your fish room to know what the levels are, makes it much easier to know when to turn off the dehumidifier.

        Do aquariums make your house humid?

        Yes, aquariums increase the humidity in the home, and may or may not become a problem, depending on the size and number of aquariums and the temperature, especially when they are in a relatively small space.

        According to Oregon State University2, tropical fish tanks and other indoor plants can add a significant amount of moisture to the air.

        Aquarium water is generally much warmer than the ambient air temperature in the home, and the temperature change in many cases can be enough to evaporate some water every day.


        I hope I have helped you find the ideal dehumidifier for your fish room.

        It is necessary to have a dehumidifier for a fish room, especially if it is a room with many fish tanks, a small space where humidity accumulates if you are having problems with mold or air circulation.

        These 5 fish room dehumidifiers are top-rated by fishkeepers and Aquarists across the internet as they are powerful enough, cover enough space, are practical, do the job efficiently, and are well priced.
