Saltwater ICH

[Chromis]

Help!,

I have a small cube and recently with the hot weather i had an outbreak of ICH. I lost 3 fish despite treating the tank with a chemical called Myaxin which is reef safe and my pipe fish was the only thing that seemed to survive. I waited about 2 weeks since the last fish died and have done a large water change and continued dosing the tank with this myaxin. I have added a yellow tailed damsel a few days ago, and this is now showing 2 small white spots. How do you irradicate this parasite??! Its not an option for me to set up another tank and treat fish for +2 weeks with copper. I've looked arround the net, but is there any way of treating this in a reef setup? what do people do who get this in a 300 gallon reef tank ? ?! surely theres a cure

the ich cycle takes about a month to get out of the aquarium, and that is with no fish in it... everytime you add another fish you are giving them a new host. also the new damsel may have already had ich when you brought him home. that is why it is a good idea to quarentine all new fish for at least 2 weeks before adding them to your tank
