So I need a dehumidifier. My fish room is about 22 ft by 14 ft and holds a little over 2000 gallons of water. The room is kept between 74 and 80 degrees. During the summer the humidity was kept in mid 70's % with a ventilation fan out the window. Since I sealed off the window to help trap the heat for the winter my humidity has been sticking at 85-90%. I want to get a Frigidaire dehumidifier but do not know what size to go with. The 70 pint seems to big. Will the 30 pint be enough or should I go up to the 50?
thank you
 
really depends on how often you want to have to dump the water. personally if i ever need one i plane to plum it into a drain so i don't have to worry about it as having played with my friends they fill up rather fast depending on what you want it set at..

its draining into a floor drain. Would efficiency be any different between the two? Looking for most efficient option
 
looking at the spec sheets looks like the 70 draws slightly more power but both have the same L/kwatt
so looks like the 50 would be slightly more energy efficient. http://www.frigidaire.com/Compare/?products=FFAD5033R1,FFAD7033R1

edit didn't see you where talking about the 30
http://www.frigidaire.com/Compare/?products=FFAD3033R1,FFAD5033R1,FFAD7033R1
seems all are rated at 1.8 L / kwh but the 30 draws a lot less power strange maybe because of bigger fans more air movement idk hopefully some one with more ex prince with these will chime in.

Ideally, you want the humidity level below 60% in the summer or mold becomes a serious concern. If it were me, I'd probably talk to a manufacturer or someone else that is expert enough to recommend the minimum size.

Obviously it may cost some money, but mold and or damage to the structure would dwarf the cost of a properly sized unit.
 
make sure u get one that can hook into a drain or you will be dumping it 2 or 3 times a day.

a lot of them has a place to hook a hose to run to a drain or sump pump.

Dehumidifiers are not energy efficient, plus they give off lots of heat.

I know but you did not suggest an alternative. The heat is welcomed.

It's going into the floor drain
 
I had to put in a 70 pint dehumidifier unit (and a couple room fans to circulate the air on timers)in my basement fish room for the same reason. Keep it set at 56%. Plumbed the drain into my a/c piping, works great but my power bill goes up significantly (+$ 60-$80 more per month) in the summer as the dehumidifier runs 95% of the time. Fortunately it starts shutting off about Sept-Oct time frame, bring power back "close" to norm (+$25-$30 more per month)

Also, I only have 6 of of 9 tanks with water in them right now down there...... (2x55, 1x40b, 1x65, 2x20L), and another 4 upstairs running. (1-75g, 1-54g, 1-37g, 1-10g)

Anyway I suppose the power costs beat having mold return however, which I found that out the first 2 months after I bought the house and added the tanks down there. That was NOT fun!
