So i found a stump that has been pretty weathered had no smell, i ran it through the dishwasher 5 times and left it on steam dry figured that would kill anything i dont want in there. anyway i decided to stick it in the tank and cross my fingers. i was wondering if it leached bad toxins in the water what should i look for in the fish, its been in there for about 3 weeks fish seem to be ok. but want to know what to look for incase i need to pull it out of the tank.
thanks
