Thanks to Capn Highliner I checked my tap water none in tap water . Checked RO/DO outlet to storage barrel none. Checked storage barrel 0.25 same as tank was testing after water change. Now I keep my wate two or three weeks always add to what is left when plastic garbage container gets low. It's been said here that you can store water up to a month . I haven't circulated it would this help. Also does anyone know why I'm picking up amonia through storing the water .Also no salt has been aded to this container.
