laser for killing reef pests?

[reefdude]

I hear someone is using a 1W laser pointer to kill unwanted polyps in his DT. Has anybody here ever heard of somebody using a laser on their tank? Can you explain how it works? Here is the video I found on youtube:

The laser focuses light and uses the heat to kill things like Aipstaisa. I highly doubt a 1 watt laser would actually be strong enough. The ones that are are illegal to sell assembled, so you buy the components and assemble it.

They are very powerful, and even a short exposure directly to someone's eye causes permanent vision loss, and you are shooting them through glass which can easily reflect the beam

Way, way to dangerous in my opinion

the guy at my lfs uses his on aiptasia and pest nems, and wears welding goggles when doing it at ALL times

I the lasers are like $400.

$400 buys a lot of Aiptasia X. ;)

IMO. your LFS guy is risking eye damage. Welding goggles are designed to block UV light and also as a general block for a broad spectrum. He should be wearing goggles/glasses designed for that specific wavelength of light.

This is very true, you need special eye wear designed to filter out the wavelength of the laser. I hope the guy at your LFS is not doing this when there are customers around

Hey, how come all the fish in his store look like this? :rofl:

(Those are eyeless fish that have evolved to living in underwater caves, in 100% darkness. Pretty neato.)

A 1W laser could almost burn through incorrect goggles. I have one from wickedlasers and it can light matches easily.
