this is gonna sound crazy but plz read this!!!! the thing is i was cleaning my sand the other day and i noticed dark patches in the sand, it looks like,um i dont know how to explain.....it looks like fag ash in the sand, i know it sounds crazy but its true, it looks like a black patch and when you move the sand it spreads,
i had a good think last night and the only thing i can think of is that it might be fish crap, where it might have been buried underneath the sand and over a long period of time its breaking down,

has anyone had this in amongst there sand,


any ideas, or guesses?????

not ready sure, I suppose it could be a little bit of uneaten food that covered up by the sand.

I cant see it being anything else but fish waste. Was it under some decor? I sometimes get a collection of waste under decor that is partially cover with sand. As i move the syphon tube over the sand to remove the waste it uncovers some more
