Sand in my new 120

Hey Everyone! How much sand should I use in my 120? I'm going to have about 150 pounds of live rock.

Do you think 80 pounds will be enough?

 

yea i think it will but i like a shallow sand bed of inch or less.

 

Will you leave it thinner under the rock and make it alittle thicker around where there is no rock.. In my Red Sea I keep a thin bed as well and really almost no sand under the rocks.. Can't see there anyway!

 

I have 20 pounds in my Red sea max. About 3 inches. I am planning on having about 120 in my new tank. It should give me about 2.5 to 3 inches.

 

yea i like to keep it thin under the rock, i hate how after 2-3 years the sand compacts against the rock and almost becomes like argocrete(argonite and concrete).

 

I agree. I like my sand to be nice and clean looking. In my Red Sea Max I have about a half inch.. I try to get my biological out of my rock. I actually will vacume my sand and replace it every so often.
