Questions:
a) When Ich or whitespots infest the fish in tank, I believe parasites will reside in the tank looking for new host, whilst I QT my fish for treatment. My question is will the corals in my main tank be infected by these parasites? Or are these parasites infectious in fish only.
b)UV treatment: How effective are they? It kills both good and bad stuff, so do we then need to repopulate the tank with good bacteria after UV treatment?
