    Default Antifreeze for Co2 laser?

    I remember seeing a video for a CO2 laser cutter and the guy posting the video used antifreeze in the water for cooling the tube. Is this a thing?

    I am trying to keep algae from growing in my coolant. After about 2 weeks, the water starts to look a little cloudy and I change it. Does antifreeze help? Does it hurt the laser tube? Any input would be awesome!

    lots of folks use a 50/50 ratio of rv antifreeze and distilled water.

    i've never had an algae problem using just distilled water (knock on wood).

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    Awesome. Thank you, Chris... Maybe I'll give it a try!
