That's the weird thing ... I'd done absolutely nothing whatsoever to the pond. It must have been some kind of strange biological imbalance ... ??
Anyway, after a week+ of a green-tinged milkshake of a pond, with no improvement whatsoever, I gave up and all but emptied it. Drastic and downright risky, I know, but I figured I had nothing to lose as, interestingly, the pH reading had climbed off the scale (alkaline) and the fish were becoming agitated. I cleaned as much of the white gunk off the walls as I could (no mean feat with a 19' x 21'pond) and refilled it.
I've jam-packed the pond and filters with Bio-Start, treated the tap-water accordingly and stopped feeding for a while. So far, so good. Perfect readings, clearish water and apparently happy fish!
Many thanks for your interest ... I've no brain cells left with this one!
