i think there might be a glitch in the sand bed calculator

[krap101]

for 1.5" its 22 lbs. but for 2" its 41 lbs. is there a glitch or reasonable explanation for this?

It looks like the calculator ignores decimals, so it's calculating for 1" when you enter 1.5". 41 is pretty much twice 22, assume rounding error or something.

Does that sound right? If you want 1.5" try entering 3" and halving the number it gives you.

I'm going to move this to the site help forum.
