when i'm removing my existing CC should i try and "sift" it and keep what LS
is there? I had a good inch at least of LS
in there and I saw LOTS of little critters in it, i can still see some worm tunnels up against the glass. I'd imagine I would want to keep as much of the existing LS
and critters as I can. if I just go in and scoop it all out I'll be throwing away a ton of little critters that everyone is working so hard to GET. Any suggestions on how to keep what i have while still removing the CC?
 what about rinsing the CC in tank water as I'm scooping it out?
if i do that and am successful I'll have about an inch of LS
on the bottom of the tank after I take everything out. If I then bury it with DS, will the infauna be able to make their way to the top?
