My Tank Thread
Hmm. Monitor and see if it progresses to more spots. I've messed up treatment several times personally, my testing human error and then cross contamination caused my issues!I forgot to answer the last part of your question, I have not used any equipment from another tank. Neither have I contaminated between tanks.
