Hello everyone I’m getting ready to treat for ick again in my tank which I’ve been doing for about two years. I’ve been using copper power for the last two years and apparently keeps them at bay parasites in there for about two months after copper treatment. I was thinking about using copper safe for the next 30 days instead of copper power has anyone use both of them and has a preference to which one works a little better. Thank you for your time. It is fish only tank 600 gallon tank
