[Wet Thumb Forum]-Adding 'live sand' (mud rather?)

[Markw78]

I have been wanting to get some 'bottom material' from the lake near where my dad lives. Its way out in the country, though there is likley some run off from the golf course. I was going to collect some mud and sand etc from the lake bottom, hopefully leaves and all kinds of nasty stuff. Then quarentine it in a 10g for a few weeks, pick out the decaying thing. May even try to protien skim it...hmmm I've heard of it working with high levels of organics. Anyways has anyone ever tried to use 'live sand' for a planted tank?
What I am after is critters more so then bacteria / nutrients etc...
