LOL, Funny this came up, as Brian stated we were just talking about this... I think it'd be a great tank tool if it works as described, But there are obvious inherent dangers... More so than with our normal tools. Most all the lasers I have researched at this level come with Suffcient eye protection. There is a risk of the beam reflecting, so most all my reserach advises against anyone else in the room at time of application... I have yet to see a report that states the laser failed to kill any aiptasia, and I have seen quite a few reviews that state they have yet to return...
I read several reports of people using them on trouble snails, shrimps, and crabs with great success, as well as mojanos and other various tank pests.
There is some worry of the laser getting into the fish's eyes, Most have reported no trouble from this, and state that even though their fish will chase a weak red laser, it has zero interest in the higher powered laser. However with a laser of this power, any angle of viewing will cause some form of eye damamge... so just having them near it risks theirs and anyone else in the room with out proper protection eye health.
I am highly interested in this... Most these lasers heat up at point to 400degf at 10m. I have watched videos and review of people killing aiptaisa more than 1' into the tank.
I plan on getting one for personal use, Tank/Survival kit, as it has some good potentials to be in a kit.
If the club thinks it's a good tool, and the board agrees, I see no other reason holding us back from purchasing.
