I'm building an aquascape and investing in spiderwood to shape a jungle-style forest.
In the past I've tried driftwood from the river and oak branches from my tree, boiling both for hours, then soaking for days. Nothing ever stayed down; they all floated and required rocks, glue, etc. Fortunately I never got as far as adding live fish, as the experiments were disasters involving insects, mold, and stinky biohazards.
This time I'm going with spiderwood from the fish store and I'm wading through advice ranging from "boil for 20 minutes and it'll sink" to "boil for 12 hours then soak for 2 weeks and then you still may need to tie it down to rocks". Even my LFS
gives conflicting advice.
So I turn to you for the real story, from your experience. What did you do - and how long did you do it - to make spider wood sink and stay sunk? It will be in sand. Thanks for your help.
