I did not add any new fish to my 240 for 6 months and one day I suddenly had velvet in my tank.Only added several coral frags during fallow. Which I know is a risk. All inverts i brought pre quarantined.
anything i can do besides do everything all over again…? What is most likely source of ich in this situation. Dont chime in unless you have been through this please. Hahaha.
any input welcome
The ONLY thing added was corals.
A few were added from a hobbyists tank who was getting out of the hobby, just a few days before the outbreak.
If it is ick, and if it were me, I would probably do the whole process over again.
