I've just started brewing a while ago but I've been keeping fish for a while now. Which brings me to my idea, when making a 5 gal batch put a gal or so of washed sanitized sand into the bottom of a 6 gal carboy during the second fermentation to bring the liquid level up and also give the yeast some little pockets to settle into at the bottom, in the sand, hopefully resulting in even less sediment in the final product. Anyone heard of anything like that done before or any reason it's a horrible idea?
