dehumidifier setting???

[PJsStuff]

I just got a dehumidifier for my fish room but im not sure what i should set it at. How humid should i try to keep the fish room??

I'd say %40-60 room humidity would be fine..

That really varies by the size of your fish room and the temperature kept. The lower the humidity the better of course, however as long as the tank remains at the temps you set and there isn't any condensation within the room, you're okay. It will take you a few weeks of tweaking to get it just right.

Im just curious (not lucky enough to have a fish room....yet. Anyway, why would the humidiy percentage vary depending on the size of the room? My thinking, which is probably flawed, is that a 100 sf room at 60% humidity is the same as a 1000 sf room at 60%. What am I missing? That goes for temp to. I agree with your statement that you don't want condensation obviously, which temp will play a part in that.

Also why lower humidity the better? I would think you would want it as high as you can and safely not have condensation. The higher the condensation the less the evaporation right?

Again not saying you are wrong at all, its just the opposite of what I would have thought. I work in the HVAC industry and deal with humidity quite a bit so thats why I am interested in the theory behind your statements.

now im even more confused. lol

i know i sweat alot less in 50% humidity than 90% sweat= evaporation on the skin to cool same effect and i would think 60% in a 100 sq ft room the worse that in a 1000 sq ft room

I was speaking in general terms because of the variables; the smaller the enclosure the quicker the accumulation of humidity and yes if the humidifier is working too efficiently the evaporation will be much greater. Because most fish rooms are small enclosures compared to the volume of water and with the multiple electronics most will run, it's better to have a little extra evaporation as opposed to condensation. Another problem is mildew when the humidity is too high; once well established it's tough to rid, especially when trying to avoid harsh chemicals around your livestock

The rooms 10x8 and there will be about 500-550 gallons of water in there.
