I recently did a deep dive into the water used in film development and what I do. Please click HERE to see it.
The short version is that I do have a home distiller which boils and re-condenses water. This allows me to remove solids that is found in the water. Measured in ppm (Parts Per Million) I can take my tap water which is around 200 ppm down to 1 ppm. This eliminates the potential of a poor reaction when I mix my chemicals. Mineral water around these parts runs around 74 ppm. This measures the TDS (Total Dissolved Solids) which is the hard salts that is found in water.
If you have very high TDS or if your water supply is inconsistent (my problem here in Jakarta) changing to mineral water will help but to completely eliminate water impurities as a potential reason for poor chemical mixtures, I suggest using distilled water. This can be purchased in many places or you can purchase a distiller and do it yourself. But read the blog post for more details!
