2w 445nm blue laser vs aiptasia
I now gave personal experience with 700mw 1400mw 2200mw and soon 3100 mw. In my opinion unless you are using something at least 2000mw and above your going to do more ****ing them off and spreading it everywhere than killing it. Also an adjustable focal length is a must! I use a piece of black cardboard stock to adjust the focal length first as its just to hard to tell shining it in the water. There is a fine line between cooking the bastards and just ****ing them off for a few days. If you cant get the right angle and focal point to completely lase the thing to pieces within 10 seconds then its not likley to kill them. The fact is there it is just not always possible to position the laser to kill them. One thing i have found is to combine the laser with some pepermints. They learn and will follow the beam around to eat the remains like bbq. Just gets annoying after awhile because you have to start shooing them away to avoid burning their little heads. Lol
