My machine sat unused for about a year.

My machine sat unused for about a year. During this time the water hoses started to break down and have pieces flaking off the outside and the inside. Figuring that it would be a bad thing to get this material stuck in the laser tube, where can I can a suitable replacement?

I doubt its the tube flaking. It’s like calcium deposits. I use silicon tubing. Available on Amazon and locally at aquarium supply and some home centers.

Yep. Mine came that way. Just flush it out with fresh water, drain it again, and then add your distilled water.

Got mine at Lowe’s. Regular plastic hose. I think it was 5/16" ID.
