JOES JUICE works every time

I have not tried Joes Juice, but have heard that it works for some, not for others. I have also heard that it is essentially Kalk paste. But Again, I have no experience with Joes Juice.

I battled mine by injecting them with boiling hot RO/DI water causing them to release their foot, I would then suck up the bodies into the syringe. I then added a peppermint shrimp. Although you may never see the shrimp he does a great job of getting the small ones, but I have found he wont touch the biggins.

I have had 3 tanks with aiptasia...my 150g, 14g, and 65g...I added Peppermint shrimp to each tank and now have no aiptasia, in the 14g it was most dramatic because it had LOTS, we added 2 Peps, came back to work 2 days later as this tank is in my office and the aiptasia were completely gone, even teenie tiny ones...and they are a nice addition to the tank anyways. I'd try that first as I had no luck with joe's juice, boiling water, vinegar etc.

yeah I think if you have lots, introducing an animal that will eat it is the best choice. that way you don't run the risk of causing weird stuff happening in your tank from various chemicals being added.

heard if you go with the peppermint shrimp method, you gotta add at least four so that you have the highest chance of getting at least one that develops a taste for it

My son had a very bad case of them in his tank. A 35 gal. and they had covered everything, a giant carpet. He picked up a Racoon Butterfly and within 3 weeks they were almost completely gone.

Get some peppermint shrimp or a copper banded butterfly fish. They both love eating aptasia.
