Now we know why pics help so much.

My first thought was you were describing aiptasia but then you changed it to copepods. Do an internet search on either just so you'll be familiar with them in the future.

Yes I got it right.

The Kalk method works great. Want to save about $10? Go to Walmart and buy a 1lb can of Pickling Lime over in the canning section for $2.20. It is the exact same calcium hydroxide as any hobby Kalk.

If you don't have any predators you could add peppermint shrimp to naturally eat away the aptasia. Rabbit fish might, copperband butterfly fish will but are very hard to keep alive if not experienced.
