Nitrate Evaporation

[Aquadicted]

I know most of you think nitrate doesn't evaporate but I keep thinking, if salt evaporates why not nitrates? I have a tank where the sump is kept near a very cold space and in the winter time I have 0 nitrates. I have my RODI with a float valve in my sump...

Thoughts?



Tank:

90G
2 tangs
2 damsels
6 other small misc fish

Salt does not evaporate and neither does Nitrate. Water evaporates faster in warmer temperatures than in colder temps. So I dont understand your theory. You have a 90 gallon tank with a small bio-load. Maybe you have adequate filtration which you did not post. Do you have a refugium? Do you run bio pellets? Xenia as a means of nutrient export? 200 lbs of live rock? A deep sand bed? What does a float valve on your RO/DI in your sump have to do with your hypothesis?

'Salt does not evaporate'
Agreed, and that is why you top off with unsalted water.

Nitrate can be converted to nitrogen gas. This happens when you have anaerobic bacteria from carbon dosing, biopellets, or a deep sand bed.

Also, i evaporate more in the winter than summer but overall water evaporation has a lot to do with humidity as well.

And as others have said salt does not evaporate.

i stand corrected.. now that i think about it all the salt i see are from splashes not evaporation.

As for my tank,

I have barebottom, regular basic sump, a joke of a skimmer which doesn't pull anything out really (coralife)

I guess faulty test kit?

Nitrate doesn't evaporate i've tested it.
