This is a bit of a long shot . I am in the uk my house has timber floor boards I have 2 tanks in mind the first one is 72x24x24 10mm glass has a weight of 108 kg the other is 72x30x24 12 mm glass and has a weight of 180 kg . my floor boards are in good condition but was wondering in 180 kg is too much and whats the best way to distribute the weight evenly.
