standard tap water will work, but if possible I would use distilled water to minimize mineral deposits. Standard safety glasses are excellent for blocking the beam. I tested a pair and they took 12 seconds to fail while in front of a 60W unfocused beam.
Thanks for the help when i get the tube running and that i will put some pictures on here will 40 watt tube burn through a half inch piece off wood un focused if it does i presume it will be slow
