I have no idea how safe this is or how the whole cooling thing works, but how about a single drop of chlorine bleach in the water?

Hey, Keith, what is the source of your water? Is it city water, well water or a cistern. Do you have a water softener of any other treatment/filter on your household water system?

I don't know if this will help, but I have some high dollar equipment in my testing lab that uses distilled water, with and additive, for cooling (the additive is basically waterbed conditioner). I don't have the laser you are speaking about, so I don't know if there would be any issues in that instance.

Use an enclosed container so that the water is in complete darkness. You can also used distilled water which will help. I use a large 10 gallon storage container with distilled water. I change the water once per year. Honestly no problems at all. I think I have had my laser for 3 years now. Distilled water will help a lot. No need to hook it up to faucet. Hope that helps.

Thank you Ron! That seems to be the simplest answer! Now the next question - do you put the pump in the water container and drill holes for the lines to the laser?

I use a 5 gallon bucket with distilled water and a harbor freight pond pump. I also have a water flow meter if it doesn't detected the water movement it will not let the laser fire.I had a pump go out and and killed the laser tube so I found a meter and installed it. Which i need to order a new one since the meter died.

this is the one i used.

Yep. Absolutely. I drilled two holes. One to pump water out and one for the return water. Also use a thermometer to determine the water temp and make sure it doesn't overheat. Make sure the outgoing and incoming water holes are far apart or you will not give it time to cool. I use a container that is large and rectangular to create large surface area for heat to be reduced. Hope that makes sense.
