a real aiptasia laser
--------------------------------------------------------------------------------
A young friend of mine is using a 1 watt laser pointer (there are 2 watt versions out there as well) to kill unwanted polyps in his DT. I borrowed it yesterday and tried it on some aiptasia in my tank (yes, I have let an aiptasia situation get out of control). I was careful and called a laser pointer manufacturer and asked some questions and read all the safety tips. The laser can shine through the GLASS of an aquarium and it isn't harmed. They couldn't tell me one way or the other about acrylic (but it's clear and their best guess was "no problem"... but that's just a guess). So I tried it on an aiptasia near the front glass. You focus the laser, light up the tentacles of the aiptasia and they shrink until into the central disk. Then holding the light on the central disk for several seconds (time depends on several factors) and it starts to shrivel up until you end up with what looks like a melted plastic lump that is charcoal colored. I also worked on one about a foot into the tank. It took a little longer and focusing was a bit more difficult, but it worked. I'm going to do more today and may even try to shoot a video to post.
Has anybody here ever heard of somebody using a laser on their tank
gad vide om det virker!!
