1) Should I add a pad or foam underneath my tank? My sump came with one already installed under it.
2) What water source should I use? I have read contradictory posts stating tap water is fine and other that condem it.
3) How reliable are rimless aquariums? I got my 90 gallon and it looks awesome but, it looks sketchy without the traditional rims. It's 1/2 thick, new and I'm thinking of filling it up half way to check its integrity. Someone slap me if I'm being paranoid.
