I recently lost one of my males to a rapidly spreading mystery disease. He was quarantined for about a week before he died this morning, but I'm a little concerned that there might be undetected contagions in the water that could harm the male that was sharing the tank beforehand. I'm going to remove the divider in the tank shortly and give Cato access to the whole tank. I want to get rid of every trace of my other fish.
Are there any really good, effective ways to clean things?
In the past, I've just been rinsing and wiping down with hot water.
