Are there any fish in the pond, or are fish any reason why you were aerating?
If there's no fish to speak of, I'd stop aerating and see what happens.
Also, if there's no fish concern, why were you aerating?
Excerpt from Robert Crais' "The Monkey's Raincoat:" "She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
