I was wondering if I should get a de-humidifier. I am going to cancel my 180 gal and upgrade to a 220. That means I will have over 500 gal of water in my living room. I had some mold before that was removed so I am wondering will a de-humidifier work. I was told that there wasnt excess moisture in the air (first mold treatment), but I was wondering if it is worth it.
