Hi, What are the Best types of drift wood or roots that sink with minimal prep and don’t leach many tannins? I’ve seen a lot of what I think is mangrove root used in aquascspe set up videos that looks fresh and dry but stays submerged when filled straight away. I’ve been there done that boiling and soaking drift wood and don’t really have the provisions where I currently live to be able to go down that path. Although I would if I had to for the right pieces. Is there something that stays submerged straight away? Or close to? I could soak over night if needed.
