Moisture in House

[woodcarver]

Just to add to the discussion,I used to have approx. 80 or so tanks in my basement rearing angels and did not have a lot of trouble with moisture ,mainly I assume because all the tanks had glass covers ?
I had a small de-humidifier in one of the rooms which did not get overworked.
Probably the open top and vigorous turnover of water in saltwater tanks greatly assists evaporation with the results we are hearing about.
I am about to get back into marines and was thinking of open top ( I suppose this is to get as much light into the tank as possible ?) but may have second thoughts on hearing the associated problems.
Is it very difficult to keep the cover glass clean ?
