1. Remove all fish from tank and place in hospital tank for 6 weeks and treat with copper. This must be done for the ich to disappear from the display tank. Pick up some cupramine and a
copper test kit you will need it as you will have to monitor the copper levels before adding any more cupramine.
2. Ich can be beaten, if the tank sits fishless for the six weeks the ich will have no fish to host and will starve to death. The 6 weeks gives the ich roughly 2 lifecycles to die off. The life cycle is 21 days, it is best practice to give it the extra 2 weeks for redunancy.
3. You can use garlic and vitamins to build the immune system, but the ich will still be present, it is best to get rid of it completely, It is a painstaking process but worth it in the long run.
4. Stress does not cause ich, stress will lower the immune system of the fish and make them more susceptible to ich. If ich is not present in the system it does not matter how bad you stress the fish out, it will not get ich. I stressed the crap out of my fish last weekend with tearing down the tank and installing a BB. Nothing had any signs of ich including the
blue hippo which is more prone to it then most fish.
5. Proper QT of all fish in the future will lead to a ich free tank. Ever since my battle with ich I treat all incoming fish for ich even if it is not showing signs of it. I too used to never QT new fish, I just put them in the display tank and let them go, I figured it wouldn't happen to me.
6. There have been reports of "reef safe" treatments for ich but are not proven like Copper has been proven for years and years. I would not chance it with a product that says reef safe.
It is not easy but after you deal with a bunch of fish in QT for 6 weeks to do it right you will QT all new fish in the long run as you will never want to deal with this again.
