Dehumidifying Options for Aquaponics Kits | Systems

Updated: Mar 6

dehumidifer for aquaponics

Aquaponic systems can raise the humidity in your home because they're essentially a large bowl of water that emits vapor.

I do not have any problem with humidity.

However, there are certain situations where humidity may be a problem.

Too much humidity can damage the integrity of buildings. Mold and mildew could also arise, which can cause health problems.

It's, therefore, essential to address this issue, and I strongly advise you to at least get a humidity tester if you have a fish tank or aquaponics system.

This article also looks at signs of humidity problems and solutions.

What is Ideal humidity?

Energy Star suggests humidity should be 30-50%

If you're unsure about your humidity percentage and would like to check, get a humidity tester.

Where humidity will not be a problem

If you live in a dry climate, the air from outside will balance the equation for you.

You may also have cooling/dehumidifying equipment that takes care of humidity.

Where humidity may be a problem

If you live in a naturally humid climate, like a hot country, or have a hot spell increasing the natural humidity, humidity may become a problem.

If this is the case, buying a humidifier and, quite possibly, a humidity tester to ensure the humidity stays at least less than 50% is best.

How to prevent humidity arising from aquaponics

Natural measures for humidity include:

  • rock salt - place this in a bucket to pull the moisture from the air

  • baking soda - place in a large container close to the aquaponics system to naturally pull humidity from the air

Other remedies for a humidifier

  • Electric Humidifiers

  • Disposable humidifier packs

Signs of humidity

  • Condensation might appear on windows or mirrors.

  • Moisture will be on the walls and surfaces.

  • Look for peeling paint or notice creaking floorboards

  • Check for scents; mildew has a moldy or smoky smell

  • Check for any dark spots or dark green discoloration on your surfaces.

Remedies for humidity

  • Spray the mold or mildew with tea tree oil or grapeseed oil

  • Open the windows more often for natural ventilation

  • Turn your AC on auto mode to keep it running for ventilation

  • Install air ventilation if you don't have any.

Finally, you mustn't skip this step, as it is best to take preventative measures to tackle mold and mildew in your home.
