If I was to run my spare HOB HOW LONG WOULD it take for it to get seeded with BB and have an instant cycled tank?
Isn't the best pic but you can sorta see it on his chin it doesn't stop swimming :/
If it is bacterial, then copper (or related) will not help. If it were a parasite, and using cupramine, then I would treat the fish in QT and keep corals in the DT.
