I think I will always have aptasia.... lol I am still learning how to combat them, I finally found a group of peppermints that will kill them and I now keep them in my sump so I can add to my tank as needed. This thing works but you have to make sure u really zap it..... it's not like u just get near aptasia and they explode. I'm getting the laser because I can then do it from outside my tank and I can use it for other things,. I will also write a review of it for masc so others can see if they want to try laser...... that being said I wasn't has impressed with the mojano wand as I had hoped but that's not to say it was bad, I think I just had really high hopes and unrealistic visions of aptasia exploding on contact never to be seen again.
