Aye. Good point about the varying layers and just killing the aerobic bacteria anyways.

Fora bit of background knowledge, this is a 33 gal refugium on a small (66 gallon) reef. Most of the rock in this particular tank has been in and out of my various reefs over the years (as small as 66, as large as 130). Has a very high worm population but I'm sure a few pieces of new rock with all sorts of critters would work well.

Already have bristles in their, saw them crawling around, probably came out of the few pieces of LR I tossed in already. Some of the bristles have died, but I think that is because they got smothered to death by the settling silt. [img]images/smiles/icon_biggrin.gif[/img]

Some live sand from an established reef would be fantastic, especially if it came with a few spaghetti worms or the like. Anyone care to donate a cup or two? [img]images/smiles/icon_biggrin.gif[/img] I can trade some mushrooms or the like. Mushrooms replicate like mad in my tank, no room for new coral right now [img]images/smiles/icon_sad.gif[/img]

I'm not worried about predators since this is a refugium with no fish/etc in it. Will add snails/shrimp/hermits later on once things are settled down a bit. For now all that is in it are a few big chunks of LR, the DSB, and a few handfuls of caulerpa.

PS: Inland Aquatics doesn't ship to Canada [img]images/smiles/icon_sad.gif[/img] Already checked them.

Thanks
