What is on in my substrate and how do i get rid of it.

[plant boy]

I keep having this problem where a whole buntch of little particules keeps accumilating in the substrate.What is it?

Particles?Do you have pics?A better description possibly?Is it poop?Do a gravel vac.

It is usually old food and poop. Does it match the color of the food. If you use flakes it is probably a greenish/brownish color, other foods may give you a sandy looking color or red, gravel vacs are good for getting rid of it. That would be my guess.
