Sand
 

I have a 90G tank that has about 4 inches of live sand in it. The tank dimensions are 48 long by 18 deep by 24 tall. Any idea how many pounds of sand 4 inches would be in a tank that size?

about 180 pounds

wow fast fingers around here. :lol:

No sand :eek: Try going bare bottom. Cheaper for starters, and lets you siphon out the detritus whenever you do weekly water changes :biggrin:

One of these weeks, I'm going to photograph all the crud we get out of one of our tanks. You'd be stunned into going with no sandbed :eek:

I had 220lbs of sand in my tank at about 6" deep so 3 cu^ft is about 220 lbs so yours is the same but only 4" deep so about 2 cu^ft..... about 150ish lbs.

I'm actually moving in July and want to get rid of the sand I have and go bare bottom so I was just wondering how much I do have so I can tell people in case someone wants it.

Thanks for all your replies.
