Ich usually comes on infected animals, not in water.

Dinos are the last stage infection IMO. Just about anything else waterborne is more tolerable if you plan on keeping SPS.

I guess that just as with blood transfusions, you'd need to make sure your supply is healthy. But when I was ready to tear down the tank, this would have been acceptable risk. Like life-saving surgery... 10% chance of survival is better than 0%.
