Substrate in hospital tank

[Aquattro]

Doug, exactly. I didn't suggest my tang got rid of it. I merely stated that after 8 months of no visible signs of ich, and no new additions to the tank, ich was still present in the system. Whether it was in the gills or hiding ina snail shell, I don't know. But it is in the system and short of bleaching the system and treating everthing with coppoer, I believe it will always be there. It just isn't anything I worry about unless I can see it.
