View Full Version : Live sand help needed.

04-14-2012, 09:02 PM
Just trying to get a idea of how many pounds of live sand I'm going to need for a 4" sand bed on a tank that is 4' by 2'. (120g)

I have no clue how to figure it all up. :roll:

Maybe this can help you, or at least I hope it can. For a two inch bed in a tank take the length and multiply it by the width (depth) and divide by 10.

48 x 24 /10
115.2 x 2 = 230.4

so that would be 230lbs then?

Yes according to my calculations. If you think about it, it takes 60 lbs to fill my 40 gallon breeder and it is no where as big as your tank and then too I am only going with a 2 inch bed. May I ask why you want it so deep?

from my readings, they say a deep sand bed should be about 4" deep. Of course, I'm allways open to others opinon.

Well, I will have to defer to them as well. In case you haven't noticed, I am a SW illiterate. :lol:

just curious as to why you are going dsb? that is a bit old school and not used often with the advanced skimmers etc available now. If this tank is a long term item, the dsb WILL reach a breaking point and could crash your tank...what about going 1.5-2 inches and getting quality live rock and a good skimmer?

every 1 gallon needs 1 in so 480 lbs if you want a 4in bed of sand

I personally like a DSB I think it provides great filtration, and I've personally never had a problem. I will agree in part with Kat, in that there are skimmers, that really are amazing! Good live rock is also good, but I think a DSB helps provide a self sufficient eco system and that's what I look for when doing my last set up...ultimately it's up to you.

Crazy eye's link is what I use FYI...

Good luck

I personally wouldn't go with 4" of live sand. I mean to each their own I suppose. Just as Kat said, I'd go 1.5-2". Or if your tank has a bottom trim just past that.

I put my DSB in the sump. Much less of a chance for problems back there. If a pump falls into your sand bed and stirs up your 4" DSB, then your tank will definitely crash. I just put enough sand down to cover the bottom of the main tank.

agreed dsb can be trouble if stired up. ive seen some amazing set ups with hardly any sand
