I'm guessing my high nutrients tank is creating giant coral killing mutant aptasia.Kalk sludge and a syringe works well (flow off). Careful the ph swing, don’t litter the battlefield with bodies too quickly. Done the boiling rodi water, another good solution. Your cocktail sounds … hardcore. These the mutant variety?
Filefish? Pipefish? Tilefish? Whatever is the fish that eats aiptasia.
