It is. Ideally you want dense hard woods, and they don't float very well.I live on the east coast (uk) and often come across plenty of driftwood and I’m wondering if it is safe to use in my tank?
Soak it for a long time to get rid of any salt. Salt (NaCl) is highly soluble, but may have soaked into the wood.If so, would it need anything doing to it beforehan
Give the soft areas a good scrub with a wire brush or similar very stiff brush. Hopefully it may just be a soft surface layer and what is underneath is much harder. If it is soft all the way through then you are unfortunately out of luck with this piece.I was able to scratch some of the damp wood off with my nail - is that possibly a sign the wood isn’t suitable?
I think it is hardwood, from the branching shape. I'd guess it may be Elm (Ulmus sp.). You may be able to tell from rings, they are quite distinctive in Elm.... Depending upon how big any piece of driftwood is you should be able to use the branching habit to make an educated guess as to whether it is a deciduous tree or coniferous.
Elm is <"ring porous">, meaning it has an obvious ring of larger pores in each growth ring.Elm is possible - it appears to have the historic larval feeding signs of the elm bark beetle and elm is present relatively nearby.
Yeah, maybe the softer more decayed wood is in the large pore space parts of the ring. Might be a good candidate for a jetwasher to blast out the softy stuff and see what you are left with?Elm is "ring porous", meaning it has an obvious ring of larger pores in each growth ring.
Ideally you want it without bark, but yes you can just scrub the lichen off.The Cherry has lichen on it, I’m assuming this will come off once it’s soaked and I give it a scrub?
I usually just leave bits of wood with bark outside until it falls off. This also ensures that <"any sap"> has <"also gone">.The piece is quite gnarled so it might be tricky to get all the bark off? Would boiling it help at all?
