I am setting up some new tanks and just got some driftwood pieces for them. A few of the pieces are at least a foot long and one in particular is about two feet long. Does anyone have any tips for getting them waterlogged so they don’t float? I was able bury a few under substrate but the others are either too big or too strong. I would have boiled them but I don’t have pots that large. What can I do to get them to sink? Right now they’re just floating on top of the tanks.
