Has anyone had experience in using MopanI wood in their tanks? It's a beautiful African hardwood that has unique and textured detail.Very dense sI it sinks immediately in aquariums. Problem with it is it needs to be soaked for a couple weeks before putting in tank because it leaches tannins which will greatly discolor water. I had a piece in my tank , it developed this whitish hairlike fungus so I removed it and boiled it but the fungus like stuff came back. I threw that piece out....the others are fine.
