Yup, because the copper treatment only kills the adults, not the eggsRaising the temp only helps the eggs to hatch quicker.
thats why i said remove the fish so that the ich wont have a host when they hatch,keeping the fish out of the tank for 3-4 weeks allows the ich to starve out.my question is being that this is almost a common thing with tangs, can they cause another break out after the first treament?Raising the temp only helps the eggs to hatch quicker.
