I would appreciate it greatly if you could tell me how much live sand to put in my future tank, and if not all 73 pounds, what other substrate I can use to fill up the level to 5 inches. Please keep in mind that my budget is very small. Speaking of my small budget, I am interested in purchasing live rock to aid in filtration, to beautify my tank and so I can later have coral and anemones. I have read that I need one pound per gallon of live rock. In my area that runs about 200 dollars. (for the 29 gallon tank) I am hoping that I either do not need that much because of the DSB or that I can add it ten pounds at a time.
