“I Change It Four Times A Day. My Birds Are Fine.”
Good. Keep doing it; our customers do too. But here is why changing it more often never fixed it: a change only resets the clock. The water is clean for exactly as long as it takes him to get to it, and that's minutes. “Dropping food in it immediately after I change the water.” From then on it stands still again, with the pellet, the dropping and the dust in it, until the next time you walk past. Four changes a day still leave hours of standing water in between, and he drinks from it the whole time, because it's the only water he has. More changes shorten the gaps. Only moving water closes them. In BirbFlow the water keeps running through a filter between your changes, so what he drops in is carried out while you're at work. You'll still change it daily. It just isn't soup by lunchtime. What changed minds wasn't a warning, it was noticing: “I clean it every day but she still puts her food in it.”
