my tank is a 180 gallon. i have a canopy but have the tops open to allow the lights to keep a little cooler.

i dont really have much surface agitation in my tank just an overflow that sucks water down into the sump

Your evaporation is consistent with my own. On my +200gal system I loose around 2 gal a day. The low tech solution is to open a window during the summer. In the winter you will probably appreciate the extra humidity when the atmosphere outside drys right out. I actually find that the humidity inside is at its lowest in the dead of winter even though the house is as closed up as possible. For smell you could run a carbon pad in a small air purifier. Or just enjoy it. I'll take ocean smell any day over Prince George black death pulp mill smell.

i dont really mind the smell that much, but whenever guests come down to view the tank they always notice it and think its because i havent cleaned it in a while
