This maybe the wrong forum so please forgive, but earlier this morning I noticed that a window in my house had a lot of condensation on it and small area seemed to have mildew or mold starting to grow. got some bleach and cleaned it all up and dried the window off. Now I got curious and found that my 60g more than likely was the cause of the problem. I also have 3 other large tanks and I am wondering if there other unseen problems inside my and garage? My 200g is in the garage and is mostly covered and water temps @76-79F. my 125 inside my home and is only covered by a canopy the 30g sump is completly open. I dont want to jump the gun here but I also dont major mold problems later either nor am I looking to quit the hobby. Is there thing that should be done. At this time I am considering removing my large tanksfrom inside the house to the garage. LMK
