Gerald, what is the difference between distilled, deionized, or distilled and deionized, or "equivalent to distilled" - presumably by reverse osmosis? I have always used distilled water, but now I'm wondering if perhaps rather than improving things vs tap water, my distilled water is the reason my XTOL always seems somewhat "weak" even when freshly mixed. Is that possible, of would Fenton oxidation only take place over time with storage. I'm confused about water.
