Dehumidifier water aquarium safe?

  • We are currently upgrading MFK. thanks! -neo
Tap water? What's that? Lol. I hear ya. It just crossed my mind since I'm spending two hundred bucks on a dehumidifier.

Hello; I read in the current issue of The Family Handyman Magazine a brief paragraph about dehumidifier water. The winter 2017 issue on page 15. States "Just don't drink it-it could contain microbes and trace amounts of metals that are harmful to humans."
The microbes could be in the air and find a good place to grow in the condensate and in the holding tank.
The trace amounts of metal might come from the metal coils and/or the welds holding them together.
The paragraph suggests using it for plants. I pour mine into the washing machine and have not used it in a tank.

Absolutely 100% agree with Oddball. Just from a bacteria perspective I would not consider it, let alone all of the other potential risks.
 
I've been doing it with four 30 pint units for about a month with a continuous water change of 1500-2000 gal a day. Have not noticed anything but I heed Oddball and RD. for very sure.

Hello; Please keep us up to date on how this works out for you.

I had considered the bacteria issue before and can see it two ways at least. One is like the magazine said and the water could become home for airborne bacteria to colonize. Another way to think is that the same bacteria can find a home around the wet surfaces of our tanks. The odds of some unpleasant bacteria finding a home in the dehumidifier may be much the same as around a tank. I suppose the dehumidifier could be cleaned with a bleach mix from time to time.
Another place in a home is the drip tray under a refrigerator or freezer. Now that I think of it I have not cleaned mine in a long while. Maybe a little bleach in it.

The trace metals are another issue. My guess is the tubes in a dehumidifier are aluminum alloy of some sort. Not sure if the are brazed together. Might take a while to build up in the water and regular water changes might keep any diluted.
 
I've treated some with prime and added into tanks without a problem or negative result. Prime will take care of the trace metals that might appear. I don't see what "chemicals" or "oils" come out of the air in our houses, that we don't breathe? The air in my house is clean.

Why would u waste money in prime to treat water from a dehumidifier when u can just get it from the faucet? Lmao
