Dehumidifier for water top off?

[FishyMcFishFace]

Anybody ever use a dehumidifier to provide top off water for a reef tank?

My last tank caused some humidity issues and my current build will be in the basement so I’m planning on using a dehumidifier. I can’t think of any reason that the water pulled from the air wouldn’t be suitable to put right back in the tank but I’ve never heard of anyone trying this. Thoughts?

i can think of several reasons.. one the water collects dust from the air,, most use copper coils and have you ever seen what build up in a duhumdifier tank? no way thats going in my reef...
what is the goal of this?

Ditto to yo^3. We all wish it was easy, and the water itself is clean, but as soon as it touches those coils and drips off it's worse than most tap.

That makes sense, it just seemed like a waste to dump all the water but I’ll stick with a traditional rodi top off.

I'd imagine you could water plants with it

As mentioned above I use it to water plants. Just tested the water reservoir for our dehumidifier and it was 64 TDS. Would not put that in my tank!

I've always been curious too. Only way to know is to test it. I have an extra ATI ICP. Let's find out.

ICP in the mailbox. Will update when results return.

Other than the coils which will be copper/aluminum, I wonder what else it picks up.

virtually all Dehumidifier water is unfit for drinking let alone tank use

Have a dedicated RO/DI unit for the dehumidifier water and maybe it will be usable.

ATI icp results:
130 silicate
2.87 copper
55 aluminum

My tap for comparison:
16474 silicate
3.01 copper
0 aluminum

Gee, I wonder what your coils are made out of.

I thought they were made of gold and fairy dust. Sad day.
