    Humidity %

    I was just wondering what would be the acceptable humidity % in a fish room.

    My average right now is around 50-55% during the day and 60-65% during the night.

    Are those percentage close to the average of everybody?

    What you guys keep your room at?

    Thanks

    I have a dehumidifier in my fish room and it keeps it around 45-50%. Seems to be fine.

    I keep the fish room at 55%.. but with the next tank running.. i might have to run an exaust fan outside if the dehumidifying can't keep up. I also keep my house at the same level.. 55-60..

    My mechanical room is kept at between 50 and 55% as well, with the aid of a dehumidifier that comes on for ten hours a day with my MH lights. No issues yet!

    Fred,

    There's a potential for mold/spores when humidity is over 60%. You may want to try to bring that level down for health concerns...

    Thanks guys for the response.

    Vince,

    My exhaust fan is on 24/7, so if I see in a few days that it is not enough I will bring my dehumidifier in the fish room.

    Humidity only go hi overnight so I might run it during that period.

    Something you want to consider when running an exhaust fan full time is your exterior humidity. At one point I ran all household exhaust fans full time only increasing my humidity levels as the outdoors hum. levels were higher than the indoors level. A dehumidifier solved my problem.

    An other thaught, once winter kicks in for real and your house heating device also starts working arround the clock hum. levels might drop to more acceptable levels. The fall and spring might be the time when you need to dehumidify the most...

    We have a 1000 gal koi pond in the bedroom and a hot tub and a 250 gal f/w tank( its a big room) the dehumidifier runs alot, youll need to buy a good one because if the rating isnt heavy enough it will freeze up and do nothing. a good one lasts about 4 years, without it swamp city
