hey jpa0741, I was wondering what you and other do that have large surface areas such as this tank and the sump. That is a TON of surface area - a lot of evaporation will occur with that. I'm just now setting up my 180 and currently have the glass covers on it while it is starting to cycle... there's a whole lot of condensation/dripping on the glass covers, so I know that there will be a bunch of evaporation if I take the covers off.... so are you, and do others just leave the tops entirely open??? If so, do you mind all that evaporation?
