I’ve done it several times you should be ok. I lost one or two corals .Flukes update: I’m still very nervous (ok, scared) to dose PraziPro on the whole tank! Since the FW dip, the Blueface angel’s eye recovered. He’s completely normal now. The French is in the same state: one eye still cloudy. The Blue had something in his eyes but now gone. The King Angel - both eyes are a little cloudy but lost appetite.
Summary: two angels are still affected: French & King. All the all fish are fine. I wish I can catch these last 2 fish and treat them but it’s near impossible
