I have a Small Freshwater Tank and I have been Real Careful not to transfer anything that has touched the Freshwater to the Saltwater Tank. Don't Really care about from My Saltwater to the Freshwater bc I have like $30 of fish in the Freshwater but Much more in the Saltwater. I wash and Sanitized My hands and wash containers in the dishwasher. Just wondering if this precaution is necessary? I had Brook like 6 months ago that wiped out all My fish in the Saltwater except Coral Beauty so I'm trying to be careful Ya Know? I heard the Freshwater Ich is no concern as is different from Saltwater so not worried about that. Any Help is Much Appreciated! THANKS! HAVE A GOOD ONE!
