There are many different ways to control Aiptasia in a fish tank. Back in the day they were seen as decor to have around the tank due to their hardiness and availability. Nowadays most reef keepers spend time trying to eradicate them from their tanks. Since they are now seen as pests there are several ways to control them whether its biologically, chemically, or manually removing them. Here's a simplified list of those ways, feel free to add more.
Biologically - Using marine life that preys on them as part of their natural diet is seen as a greener way to treat the problem. These would be things like copperband butterflies, Molly Miller blennies, aiptasia eating filefish and peppermint shrimp. However you have to keep in mind not every fish/shrimp will go after them as they don't always have a taste for aiptasia.
Chemically - Using things like Aiptaisa-X, Kalkwasser paste, or Vinegar or Lemon Juice can be directly injected onto/into the aiptasia killing it effectively, if this accidently blows into other corals or too much is dosed it can cause some issues in your tank, so care should be taken when going with this route.
Manually - Manual removal can be easy and tricky depending on where the aiptasia is located, if it's on a smooth rock or the glass then it's as easy as scraping it off and sucking it out during the water change. If its in a hard to reach spot it becomes a lot more tricky as you have to remove the entire rock and treat it. You can do this by either drying it out for a couple of days to a week in the sun, or soaking it in a solution of vinegar and water OR hydrogen peroxide and water, but this also kills off your beneficial bacteria.
Whichever way you choose is up to you, best of luck!
