My tank had a really bad case of ICK. We had to move it anyway so after my last fish died we just emptied it out and cleaned it out and mover it. I've had it setup up (with water in it, aeration is on as well as the heater, it's at 77 degrees). I heard that if you've had ICK, without a host (fish) it will just die off. We wiped everything down wirh hot water. Wanted to wait till I'm ICK-less before I started the cycle azgain. I bought some aquarium salt to use just in case it comes back. In your experiences how much longer will I need to wait?
