I have noticed on one of my pieces of bogwood that it keeps getting this whitish film on one part of it . Its like fish mucus . I have even power washed it but it has still come back . I took it out of the tank today and in the affected area it smells a bit like mushrooms
does anyone have any idea what this is or how to get rid of it ??? ............. before use the wood was soaked for 2 months in water and then i put no end of boiling water over it and scrubbed it before i put it in the tank , so i dont think that anything living could be the cause . But if anyone has any helpfull information then please let me know .
