Ok so I bought a piece of zoomed mopani in PetSmart. Got it home soaked in very hot water added to my turtle tank::: released some tannins But no major murkyness... all is good... same time I bought a fluval mopani piece on amazon. I used the same procedure and stuck in a spare fish tank Because I was suspect for some reason though this is first time I’ve used wood in a tank. The water is super brown, smells awful, and started to get slimy after two weeks. It’s not heavy like the zoomed piece and semi floats. Has anyone had experience with the fluval mopani wood? Did amazon send me something that’s not legit. It’s a nice looking piece but I don’t know how to proceed!
