glass top yes or no

[SeaHorse_Fanatic]

I have glass tops over all my tanks now. Yes, I lose some of the light's intensity etc. but my open top 210g with 75g sump used to lose 10-15g per week. All that water vapour into the house's interior cannot be good for the house or its occupants (ie. mold/mildew). Glass tops has me down to 5-6g on the 165g with open 90g wide sump. I'm sure I could cut this down even more with glass tops over the sump. In my house, any open top tank loses two to three times as much water through evaporation than a closed glass top tank. With severe MTS, this is a real concern.

I was thinking of going mesh top but the evaporation rate increase has me hesitant to go that route. And yes, I am wrasse-crazy so the tops serve a double purpose. But mainly I have them to reduce evaporation.
