Be confident in your purchase we're an Authorized Frank's Tanks Dealer. How cool is that?!?!? (NOTE: DO NOT PUT ON CORALS) If you've ever had aiptasia anemones in your prized aquarium, you'd certainly understand how this product got it's name. Aiptasia anemones can kill your corals and even small fish. They are capable of stinging and stressing even larger specimens. So why not just kill them??? F-Aiptasia Killer does that better than the other products on the market. F-Aiptasia Killer sticks to the aiptasia to deliver it's death blow to the anemone! If you have ever used other products, you may have noticed that it often causes the anemones to reproduce and you end up with more of them than you had before! So forget the idea about injecting aiptasia anemones with boiling hot water and lemon juice. Cover the anemones with this product and you will soon say F-Aiptasia like so many others have! And when used properly, F-Aiptaisa will not harm corals or other inhabitants!
