Ich infested tank

[expert]

Dear Bros and Sis,

Recently started a new marine tank, cycled less than a week and bought quite a numbers of fishes and all contacted with ichs(All dead now).

Did a 30% water changed, run for another 1 week and i bought some sharks than i realised the tank need to run empty for at least another 4 weeks to fully wipe out the ich.

Was told that sharks are not easy prey for ich and so far so good. I know copper can kill but it will harm the sharks.

Any good recommendation that i can kill the ich and not harm the shark?

Get the shark a new home. Restart your cycling process. Wait till it's fully cycled till u add livestock

Bro .. Even if it's not an easy prey of ich, I dun think it will be fair for the shark to be swimming in such waters.

If u intend to copper ur tank, do note that u will not be able to keep corals in future as copper would be present in your rocks and be harmful for the corals
