I would like to get a 125g, but with my floors currently upstairs this is impossible. Is their some simple way to make my floors so that they can carry more weight? Or a way to make the water lighter? I have always wanted a bigger tank. Money has never been a problem, the lone challenge has been the floors. The upstairs of my parents house was finished less than 20 years ago, my room is carpet and according to my parents their is no support in the upstairs. Nothing more than wood pillars and plywood. Loosely scattered wood pillars. The room is 14' X 14'. The 100g fish tank is less than 2ft from where i sleep. I have a pond aerator and a dozen hob filters. I just learn to live with the noise. It doesnt bother me. The floor around my 100g is about 1/4" uneven. It was this way even with a 55g. I have been desperately wanting a bigger tank. But with a major eathquake looming around where I live expected within the next few years I don't want my room collapsing under the weight. I am in desperate need of ideas. This is of extreme priority.
