Hello all. First post here. I've done a search both here and on reef forums and most of the info is dated. I'm interested in a 3w 445nm laser for reef aquarium use. Some of the terms I've run across are focusable, g2 lens and laserbee verification of power. I've looked as Sanwu and Survival Laser and see some in the $250 range. I'm not opposed to a reputable member here building one for me if I get a better laser for that $250 or save some money for an equivalent. Any help and advice is appreciated. Give me a link or some contact information if possible. Thanks, David

Welcome to the forum. First off, why do you need a 3W laser for an aquarium? What size aquarium are you using it for? A 3W laser can be extremely dangerous, and you might fry your fish. :undecided:

I've got a 120g. I would need to reach up to 18 inches to zap what I need to take care of. I'm aware and even paranoid about the safety issues. I was told the higher the power the less time it would take but I'm certainly open to suggestions. I have messaged a few people that have them and they suggest 3w would be a good choice. Some have gone as high as 5w.

In that case I would recommend purchasing the Challenger II 445 from Sanwu. For 3W with G7 lens it is $218.00, well within your range. The G7 lens will likely be best for your purposes as it can burn well at long distance. Here's a link: Challenger series

Thank you Sta. I had not considered the G7 lens. That Sanwu looks good.

Don't forget to include a pair of laser safety glasses for the wavelength you are using in your budget. The Eagle Pair from Survival Lasers are recommended here often. :)
