I have a 10 gallon aquarium with 6 neon tetras. I am using a cooling fan to keep the aquarium cool in summer when the temperature is getting hot. The cooling fan does evaporate water from the aquarium. while near the aquarium you can feel the air bouncing off after hitting the aquarium water. I read somewhere if the evaporation was agitated, microorganisms like bacteria and germs can also evaporate with the air. Should I be worried because I can not move the aquarium due to space and I stay most of the time in the same room near aquarium.
