It's been a struggle trying to find the right solution to get rid of ick but I've finally found the best way to get rid of this disease. I tried Copper Power in a quarantine tank without any sand and left me fish in there for about 4-6 weeks and found that it kills the ich better than any treatment that doesn't require as much attention as hyposalinity and other copper products. With Copper Power you just add the given amount and you don't need to test for Copper. When using the product don't run it with any type of carbon. And make sure you have a desperate holding tank to quarantine rather than your main tank because it will kill your invertebrates and coral.
