Does humidity affect a reef tank?

[DracoKat]

I live in a condo, and they recently worked the boiler room in the basement. Now I notice on rainy days like today, humidity is up in my condo.

Aside from evaporation- does humidity play a role in tank chemistry? Anything I should keep a lookout for?

Not really with out tanks....however, when my humidity is too high in my basement, the carbon dioxide seems to increase affecting the ph....but that's all I've ever seen happen....

The higher humidity, the less amount of evaporation......and vice versa.
