Well, the Laser is great for Majono's and depending on the size of the Aptasia. I think I will be up grading to the new 3-watt model for bigger Aptasia or anything else (current laser 2-watt). I have used it on blue clove polyps and majono's great efficiency. Then again I have one that eats Joe's juice as a snack...HAHHAHA...and survived a boiling water injection and a lemon juice injection. I have a bulldog-Aptasia! But yea, other than the occasional steroid pest, works pretty good. Until I find a proprietary mix that kills this thing(retirement), makes good target practice.
