I have recently begun using a red and black Chinese laser 100w and have arriving an industrial water chilling cw-5000 links at the bottom of the post if it is important.
To this point I have been using distilled water and I know that down the road this has the potential for fungal/bacterial growth. So my question is what I should be using?
I have read that pink RV anti-freeze is a good option. If so, what should it be diluted to? Or is it even a good idea?
What are you using, and what additives if any do you add to prevent bacterial/fungal growth?
Thank you for taking the time
