During last spring/summer i went out at what first started off finding my own unique pieces for my aquariums. After finding a huge tree root (size of half a car) i decided on the pieces i wanted and tried selling the rest on various sites, i was amazed how many people within a couple of hours had responded to my adverts. By the end of the day they were all sold, and i still had people asking if i had pieces left.
I decided to go out again and make some pocket money from it, i will be out again when the weather turns better no doubt !
The thing with cleaning it is that the more unique the piece is the more twists & turns it has making those hard to reach places almost impossible to clean properly. I have bought a huge metal trash can that i place on top of a burner to boil the wood for an hour with salt. I then power wash the piece, then place it in a rubbermaid tub and scrub it with a hard scrubbing brush, then it goes back in to boil for 15 mins.
Maybe the above is a little extreme but with me selling the pieces i have to make sure there is nothing on the wood that can cause harm to their fish. . . . otherwise i would have a lot of people at my door wanting to hit me with the wood !!!! ha ha
