Why not join the bare-bottom club?

You don’t need sand in your tank as long as you have a good amount of live rock. Not as nice looking but man is it easier to keep clean! I personally love the look once the bottom gets covered in coralline and some GSP....looks like my front lawn lol

Thanks for the reply, Ray
Not a big fan of the bare bottom look, plus I always will have a goby in my tanks. I like their personalities.

The whole H2S thing is blown out of proportion too much. Unless you have a deep sand bed (4+ inches), I wouldn't worry about that.

I used the http://www.jlaquatics.com/product/cs...-+30+lbs..html
which is still fine enough for the wrasses and goby, but doesn't float around the tank.

Thanks Brad, only 1 1/2" at the deepest so shouldn't be to bad. Would it be an option to just layer the heavier material on top?
I'm thinking that the heavier material will settle to the bottom and I will be back at the same place.

I'm sure you have Denny, got lots of critters that keep it stirred.
I think my favorite is the Giraffe turbos. Don't see them for weeks, then you see the periscope and up they come.

QUOTE=Faithinc;698910]For my 55g, I've gone with a mix of 50lbs of the first Caribsea mix you posted, with an additional 20lbs of fine sand. The fine will eventually sift to the bottom, allowing good sand-bed growth (worms and w/e you're looking for if your into sand beds) while the top shale-shaped sand has kept my bottom from turning up a dust storm every time my power heads + return are going.

I don't know if this substrate would be good for pistol shrimp. As i've read: Pistol shrimp will dig into rock if they don't have a solid packed substrate they can play around in. If you really want one of these little guys, I'd buy a really porous rock and bury it under your stand with just the top sticking out. At least then he'd have something solid to dig into.

But I'm just a noob and wikipedia is my friend.[/quote]
