How much CC for 125 gallon?

How much crushed coral would you need for a 125 gallon fish tank?
I am talking absolute minimum for a FOWLR tank

can you just go with a minimal amount of sand? CC in the long run will be a mess for your tank, and an even bigger mess when you have to remove it.

none. Its that easy

Go get sand instead because cc will trap detritus (sp?) and make the nitrates rise.

I am also setting up a 125 gallon, but I am using sand. 200 lbs.

Ok, then whats the smallest amount of sand I can use? Im hoping like 80-90 lbs?

 

[cartman101]

I dont remember what I used but that seem about right. Go to your lfs and ask. I think I used somewhere around there.

Since I am new, I definetly not the one to make a recommendation on minimum amount of sand. I think you need to have at least a 1" sand bed if that helps at all. Not sure how much that would figure to be.

OK, heres the scoop.
The amount of sand depends on a few things. Do you want to keep animals that burrow and live in the sand? do you want it to be adenitrificaton bed?
If the answer to the above isyes,then you need a minimum of 4 inches of sand in the bottom of your tank.
Do you just want something ornamental? Then it doesnt matter. You coulduse crushed coral, just a little to cover the bottom and make sure to vacuum it well when you siphon off the water to get rid of that acuumulated detritus.
Sand gets stirred up easily when our tanks are cleaned, it also requires sand sifters of some kind to move it around. Yes, a deep sand bed is a definite plus in aiding the natural processes of life (hows that??) but that is a DEEP sand bed. A shallow one really is pretty useless.

No Cc, Sand!

Sand will go about 1 bag per foot of tank. 6 foot tank, minimum of six bags and thats about a thin 1" too.
