Isnt that a little bacterious and gross for the tank?Just go for a walk through your local woods, or head the local water(lake, river, pond estuary) and start pulling out branches. You will be amazed what you can find for free! I have 3-4 good size bits in my back garden that i've plucked from various places. They would cost a small fortune in shops.
