How much Sand?

[aceiswild7]

ive had my 125 for a while now and im setting up a 180 and im going to raise my 125 on a platform and use it as a gravity feeding refugium to the main 180. my question is how much sand do i need for my 180 to get the desired 4" bed? i have it in my 125 now but its been a while and i have no idea how much i used. the 180 is 72"by24" .
Thanx

I just filled my 125. I used 60 lbs of ls,and 120 lbs of Yardright. I have a 4-6 inch depth. So, if you have a 180 I would guess that 250 - 270 lbs of sand would do the trick.

how much sand do i need for my 180 to get the desired 4" bed?

the 180 is 72"by24"
72x24x4x.0579=400.2048 lbs sand for 4" DSB
...so about 400 lbs sand

That 400 seemed a bit much, but I used your formula to reverse calculate my tank. Looks like its dead on. Is the LxWxDx0.0579 a constant? I like it if it is.

Southdown play sand from Home Depot. Great stuff if you can find it. You may have some luck being in the Northeast!
Good Luck!

I found my Yardright,same thing as Southdown,on the merchandise for sale message board.
Try ---- too.Somebody else had some for auction there not too long ago.
