Hi, I'm in the process of setting up a 10 gallon tank that I want to have a land area in. I want to use a piece of glass as a shelf of sorts to hold the land/soil area. I'm totally new to tank modification and could really use some help. Does anyone know offhand what size cut of glass that would be to go from one side to the other? Also, what is the product called that I use to stick it in place? Also, will it need any kind of support underneath in the middle area or anywhere else, or will the adhesive be enough? I know I will have to get a second piece of glass cut to make an inch or so lip to hold the soil back and all of equal length to the other cut. For all needed materials, what is the estimated cost? Am I forgetting anything? Again, any help would be appreciated.
