I am turning one area of one chamber in my IM 16 gal nano into a refugium. Any idea on where I can get small amounts of 'mud'? Most places seem to be selling no lower than 10 lbs, and I at most need 3.<br>I suppose I could use what I needed in the refugium and put the rest in the display tank....I would love the added diversity in the micro critters, but don;t want to create a DSB. There is already 1.5 in 'live sand' in there now.<br>Thoughts? Suggestions? Links to suppliers? Sell me some of yours? <img src="https://www.reef2reef.com/forums/images/smilies/cutemoticons/cutemoticons/bigsmile.png" border="0" alt="" title="Bigsmile" smilieid="377" class="inlineimg">
