distilled water vs Reverse Osmosis water

[SuperChuck]

Pick up a gallon of distilled water for $1.50...

Use DISTILLED water. R/O water is not good enough. Your filtered water will get the ppm's down to 5-15, distilled waters ppm's are ZERO.

The western was probably pre-charged with 50/50. Just add distilled water and off you go.
