Aquarium Advice Freak
I have a 72G bowfront aquarium that I am about to change the substrate in. I was using the Sand Bed Depth Calculator on here to figure out how much sand I would need for a 1.5 - 2 inch sand bed. It says I need between 33 and 66lbs of sand. I thought I had been told that a good rule of thumb is 1lb per gallon so I bought, but haven't added, 80lbs. Is this going to be too much? I've heard that you either want 1.5 inches or a DSB of 4+. What issues are there with having a sand bed inbetween these two depths?
