Cleaning and flushing our nitro system , but using water since there isn't cold brew yet (will later flush out w CB). Is "nitro water" supposed to look cloudy? I've flushed out about a gallon now , and maybe it's just because of the infused air , but it still looks cloudy. When I let the water settle there's still a some "cloud" that is at the top, but I can't tell if that's the air or remnants of cleaner or nitro. I've never cleaned the nitro system before
