After 5 1/2 yrs of being ich free, I introduce ich to Doofus
2 weeks after I rearranged the tank, I received 2 boxes of corals and lacking any place to quarantine all of them for the required time and because some of them were in need of tlc I placed them in the tank. 2 days later doofus had a few spots, this morning (exactly 1 week later) Doofus is covered.
