Welcome to the boards!! Kick ich is a product designed to help keep ich off of the fish. It does not kill ich though. No medication can kill one invert (ich is an invert) and not kill others such as your shrimp, stars, etc. The product is alright at keeping ich under conrtol, but will not eliminate it from your tank. Do you want to try to control ich or would you like to kill it? If you are just looking for control then you will have to be sure that your fish are as stress free as possible. This includes making sure that the water parameters are optimal, there is no fighting/chasing going on with your fish and feed them a very high quality diet dosed with a rotation of Zoecon, vitachem, and fresh garlic. Continue to use the kick ich as well. All of this may or may not help your fish fight off the parasites.
If you would like to kill the ich then we can help you with that as well. We will need to know what livestock, including any inverts and live rock, are in the tank and if you have a quarantine tank set up or not.
