Hey, Eve! First of all, please know that there are NO dumb questions. Even the most experienced of us hobbyists are able to admit that we have some questions that we don't know the answers to. Others are so dumb that they think that they've learned enough and that they have all the answers and people like that are a danger to your aquarium! Your will to ask the questions will make you more knowledgeable than you can imagine!
As for the aiptasia, I would love to encourage you to at least try my product! It has been an incredible breakthrough for the hobby! I can't and I don't take full credit for the product. There are some other players in this. I assure you that the product is highly effective. It will not allow the anemones to send off spores that produce other nuisance anemones later. I don't know of a single product like this and prior to being a part of this, I have tried them all. I have been in the hobby for over 30 years....long before most but again, I don't know every aspect of this industry or this hobby. But one thing that I do know is that THIS product works! Am I boasting a bit because I have something to do with it's creation? Yes indeed!!
I have no reason to speak against any product or even another method. And I won't! All that I am saying is that THIS PRODUCT WORKS. I have never met any of the people who have given this product a great review. They aren't paid to say good things about the product. These are people, like so many others, who have tried products that didn't work long term and then tried this one. There are many ways to 'handle' issues that arise in our aquariums. But this has been the best defense for aiptasia that I have ever seen or used!
